The KetoScan is an electronic ketone tester that measures ketones in breath, specifically, the acetone concentration in your breath. As the relationship between breath acetone concentration and ketosis are closely correlated, the KetoScan makes an excellent device for accurately measuring ketones in a convenient and reliable way.
The more fat is metabolised into energy, the higher the levels of breath ketones there are. With the KetoScan Mini, you can monitor and track your progress in actual numbers and make improvements on fat loss. FDA-approved as well, the KetoScan Mini is the best ketone meter choice for anyone on a Paleo, Ketogenic or Low Carb diet wanting to monitor their fat burning progress with quantitative data!
Accurately measures breath acetone concentration at 100 resolutions (0.0~99) using a PPM (Part Per Million) measurement. The KetoScan provides you with 13 levels of ketone test results that are simple and easy to understand.
Check out the Ketone Levels Chart at the bottom of this page.
The highly sensitive acetone sensor in the KetoScan is protected with self-diagnostics for sustainable, long term use. To maintain itself as an accurate ketone meter, the KetoScan Mini also notifies you when a calibration is required (after 300 tests). The device will lock after 320 tests to prevent itself from providing inaccurate results.
Read the KetoScan FAQs (tab) for more information on calibration.
The KetoScan Mini can be paired with its very own KetoScan mobile app, where all ketone test results from your ketone meter can be tracked daily, weekly and monthly right from your smartphone. Additionally, you can add your food consumption, track calorie intake and synchronise the app with iOS Health, Samsung Health and Google Fit - making it an excellent all-in-one health app to help you reach your fitness goals.
No other diet apps are necessary to reach your fitness goals. Just blow into the ketone breath meter, get your score, leave comments, track calories, and take photos of what you ate - all within the KetoScan app.
The KetoScan app will remind you to be cautious of the various factors that can affect your ketone test results. For example, avoid brushing your teeth, smoking, and eating foods 30 minutes before taking a ketone test for a more accurate breath acetone concentration.
The KetoScan simply requires a strong and steady blow to analyse your breath for ketone levels. Follow the easy step-by-step instructions on the KetoScan mobile app for accurate and consistent test results.
The KetoScan ketone breath meter and the mobile app are connected seamlessly, so if your exhaled breath is insufficient, the mobile app will show a message and notify you when a re-test is needed.
Are you on an exercise program, or being coached on your dietary intake? You can send your ketone test results to your dietary coach, personal trainer, and even your physician.
Share your results and stay motivated with your diet or fitness buddies. The KetoScan app displays weekly rankings between you and your friends, so you can motivate and even compete with each other to reach your goals.

Each KetoScan Mini Ketone Breath Test Kit comes with a user manual, carrying pouch, USB cable and 5 mouthpieces including a polythene pack for mouthpiece storage. A rechargeable battery is included with this ketone testing device so you can get started on taking a ketone breath test straight away.
The KetoScan Mini will display results as Ketosis levels 0 to 10, based on the breath acetone concentration detected. The best ketone meter reading is Level 10, which is the optimum level of ketosis at 10ppm of breath acetone concentration. Level 0 shows that your body is not producing any breath acetone, and therefore your body is not in ketosis (early ketosis starts at 2ppm). On the other hand, if the KetoScan Mini shows up with levels "Caution" and "Danger", then it has detected an excessive level of ketosis, which can be dangerous. Refer to the KetoScan's Ketone Level Charts below for more information on how to understand your KetoScan ketone test readings.

To measure ketone levels with acetone, the KetoScan needs to detect PPM levels at extremely low concentrations, so a very sensitive sensor is required. If you use the sensor frequently, it will be inevitably contaminated by foreign objects mixed in with the respiration, which requires readjustment of the precision of the device through the means of a calibration. The device will display a calibration message after usage of 300 times, and it will automatically lock the use of the device after 320 measurements.
Please contact us at 1300 800 200 for the calibration of your device. Each calibration will be $75.
When and how often to test ketones will depend on what you’re looking to find out.
If you’re looking to compare whether you’re keeping in ketosis from day to day or week to week, then it makes sense to test at the same time (or times) of day. This will ensure you get consistent results.
As ketones vary through the day, and are affected by different types of meal and exercise, you may want to test at different times through the day to see how your level of ketosis varies, in the beginning of your keto diet.
After you have a set the best time of the day to test yourself, if you want to check your urine ketones day-to-day, stick with that specific time, like in the morning or several hours after your last meal of the day, for best comparison.
We recommend that testing once a day would be good enough. Note also that the unit gets locked and will require calibration after 300 tests, so if you test too often, you will need to send your unit back for calibration more frequently.
The KetoScan ketone machine utilises a patented self diagnosis technology. If the equipment has not been in use for a period of time, gas lingering around the house may enter the equipment, changing the zero-point (base line) of the sensor and as a result affecting the measurement accuracy. KetoScan's patented technology is able to perform a self check on the equipment status during the measurement preparation stage, and if it decides that the zero-point is incorrect, it does not show the measurement after a blow by the user, but uses respiration gas of the user for zero-point adjustment and requires another measurement again. Self-diagnosis operates automatically and according to the situation, so even if it occurs frequently, it is not that the equipment function has degraded, but rather it is for more precise measurements.
The KetoScan comes with 5 disposable mouthpieces. You can purchase additional mouthpieces from Andatech.
There is a sliding built-in mouthpiece for personal use. However, if multiple users use the same device, then it is highly recommended to use the disposable mouthpieces for hygienic purposes.
The disposable mouthpieces are designed for one-time use only but can be re-used if you rinse it with running water and dry it thoroughly before re-using them. Make sure they are clean and dry before use, otherwise you will damage the KetoScan's sensor.
The results will not be the same. The main reason is because blood testing measures BHB and it is expressed in mMol, whereas the Ketoscan mini's breath tester measures acetone concentration which is expressed in PPM (Parts Per Million). Two types of meters measure the two different ketone-bodies so it could not be compared 1:1. Breath testing result shows more precisely and is able to show a smaller amount of ketone state from your breath compare to blood testing.
If you have blood readings from 0.5 to 3.0 mMol, then Ketoscan mini will show from earlier state to optimal level of ketosis with PPM resolutions. For the detail of PPM level for each ketosis state, please check the our ketones level chart guide under the Product Description.
Ketones, also known as 'ketone bodies', are byproducts of the body breaking down fat for energy. Ketones and ketoacids are alternative fuels for the body that are made when glucose is in short supply. They are made in the liver from the breakdown of fats. Ketones are formed when there is not enough sugar or glucose to supply the body's fuel needs. This occurs overnight, and during dieting or fasting.
For a person without diabetes, this process of ketosis doesn’t become an issue. In fact, ketosis is beneficial for those wanting to lose weight as if effectively helps to burn fat for energy. However, when you have diabetes, you can build up too many ketones in your blood -- and ketone levels that are too high can become life-threatening (a condition called ketoacidosis).
Ketone bodies are composed of 3 ingredients: acetone, β-hydroxybutyrate and acetoacetic acid.
There are three ways to measure ketones in your body:
1. Urine sticks – measures the levels of Acetoacetic acid - cheap and easy to use, but not very accurate.
2. Breath meters – measures the levels of acetone in breath - more accurate than urine sticks and affordable.
3. Blood ketone meter – measures β-hydroxybutyrate through blood - the most accurate method available but very expensive.
Breath ketones are a helpful indicator of your body's level of ketosis.
When you are in ketosis or body fat lipolysis, acetone is released as a by-product and is detectable in your breath. As body fat lipolysis progresses faster, the amounts of ketone in your body increases. This allows us to find out how fast body fat lipolysis is occuring by measuring the amount of ketone bodies produced by our body. In the case of ketone breath meters, the amount of acetone in breath is measured.
Unlike other methods such as urine strips or blood tests, breath ketone levels do not depend on fluid logistics, minerals or vitamins. The more fat is metabolised into energy, the more breath ketones there are.
There are various pros and cons of each method of measuring ketones. Here is a simple breakdown for each of them - we hope it helps!

KETOSCAN is a breath ketone meter that monitors your body fat burning rate. The creators behind Ketoscan looked at how much body fat burning could be maximized on a regular low-calorie diet with exercise. A clinical trial was conducted on how accurately the KETOSCAN mini can measure body fat burning rate in a woman in her 30s.
Put to the test:
Clinical Trial Conditions:
| Location: Sentech’s laboratory
| Subject: 1 Woman in her 30s
| Period: 28 Days
| Meal: Low caloric dietary meal (Consumed 70% of recommend calories + low carb)
| Exercise: No exercise Day 1~19 / 1H per day of treadmill exercise Day 20~30
| Experimental purpose: Evaluate the accuracy of KETOSCAN’s body fat burning measurement
| Measurement: 3 times/day (at the same time every day), Brac measured by KETOSCAN, Body fat measured by Inbody
Results of the Ketoscan clinical trial:
Subject’s Result
- Average Brac during 30 days : 5.4ppm (LEVEL 5)
- Average Body fat burning rate during 30 days : 3.1gram /hour (75gram/day)
- Brac increased significantly on day 20 once exercise was introduced into the trial
KETOSCAN’s calculation
LEVEL 5 on KETOSCAN means 3.8 gram of body fat is burning per hour
Actual body fat burning rate 3.1 g/h of subject and 3.8 g/h of KETOSCAN’s pre-set value are about the same.
Ketone bodies are composed of 3 substances: acetone, BOHB (β-hydroxybutyrate), and ACAC (acetoacetate). The creators of Ketoscan conducted its own clinical trial on 5 men to prove the deep correlation between acetone and BOHB.
Put to the Test:
Clinical Trial Conditions:
| Location: Sentech’s laboratory
| Subject: 5 men (20s~50s)
| Meal: Ketogenic dietary meal (Low carb high fat)
| Experimental purpose: Analysis of the relationship between breath acetone measured by KETOSCAN and BOHB measured by blood ketone meter
| Measurement: 3 times/day (at the same time every day), Breath Acetone measured by KETOSCAN, BOHB measured by blood ketone meter
Results of the Ketoscan's clinical trial:
As shown in the chart above, the increase and fall of breath acetone and BOHB move in the same direction, and their very strong correlation is consistent with what was published in the previous scientific articles.
However, since the dispersion is large, it is difficult to present correct BOHB reading directly from the acetone level.
So, is there any way to predict blood meter readings from acetone levels?
There is. Although many variables exist, it is difficult to predict the absolute value, in conclusion, from the acetone level, the average value of the blood meter over the past few hours can be predicted.
The blood meter measures the concentration of BOHB. Since BOHB is a substance used as a fuel, its concentration tends to change rapidly from time to time depending on energy consumption activities. On the other hand, since acetone which is measured by KETOSCAN, is not an energy-based substance, only some of it is emitted through respiration and skin, while others are accumulated in the body, so the variation of the result is relatively small.
Therefore, even if the concentration of blood ketone meter (BOHB) decreases rapidly, KETOSCAN (acetone) has less variation in the number, and as a result, the current concentration of acetone can be considered as the average value of BOHB concentrations over the past few hours.
The stable result of KETOSCAN
Assuming that both the KETOSCAN and the blood meter have conducted a test at the same time every three hours, and both results initially correspond to the ketosis state but why does the blood meter suddenly drops to 0.1mM which is considered out of ketosis?
| 00:00 | 03:00 | 06:00 | 09:00 | 12:00 | 15:00 | 18:00 | |
| KETOSCAN mini | KETOSIS | KETOSIS | KETOSIS | KETOSIS | KETOSIS | KETOSIS | KETOSIS |
| Blood meter | KETOSIS | KETOSIS | KETOSIS | KETOSIS | KETOSIS | KETO OUT | KETO OUT |
① If the body consumes BOHB rapidly for various reasons, such as exercise, the blood meter reading drops sharply and becomes out of ketosis state.
② Since the acetone is not an energy source, the level of acetone is stable and keeps you in a ketosis state.
>>> Therefore, KETOSCAN levels remain at ketosis, but blood meter indicates that lower BOHB is a temporary result rather than a “keto-out” i.e. being out of ketosis. If you go on a continuous diet at this time, the BOHB on blood meter usually will be recovered soon.
The reason why blood meter readings change so much, even though my body remains in ketosis, can be found in Sentech GMI’s clinical trials and scientific articles, as shown earlier. Therefore, acetone measurements may be better than blood measurements to ensure a stable understanding of the change in ketone status.

With KETOSCAN, you’ll be able to see the changes in ketone levels precisely and save money from not needing to buy expensive blood strips.
"I love this little device. It’s accurate and easy to use. I no longer have to pee on little plastic strips or painfully prick my finger for blood. I can check my ketones discreetly and more importantly sanitarily while on the road. No more carrying around test strips and needles or finding a place to properly dispose (no flushing allowed) of the used plastic pee strips. (Gross!) The app works great too. Recommend."
"...this product super exceeded my expectations. I had been on keto for over a year and it was so hard to track my ketosis that it became extremely frustrating for me and I nearly gave up. ... I needed new motivation this gave me so much more than that. Not only have I lost an additional 6 pounds in 1 week i’m actually excited and happy to be back on keto 100% because now that I have a way to keep track it put me back on track !"
"The Ketoscan is fast and appears to be accurate. It will not give a reading if it detects too little air volume, and it indicates when to stop. This should help with inevitable variance due to different amounts of air. It can be used with or without the app, and its output is ppm."
"Compared to paying for the blood testing strips-- this device wins hands down as far as expense. I also really like the app-- it provides great data and a way to track things over time."
"I love that this does not involve peeing on a test strip or pricking your fingers for blood! It's easy and syncs right up to an app. It comes in a little zip case that allows for easy travel, so I keep it on me all the time! Great product and I can't wait to get to know how certain foods affect my ketone by using this!"
"Love this meter. I’ve used strips and blood meters but this is the most accurate. I’ll test back to back to back and readings are nearly the same each time. ...so far this gives me the confidence that my measurements correlate with what I’m doing. It helps me stick with what I’m doing."
"I have been on a low carb/ Keto diet for 6 Months. I recently discovered this tool. I really wish I had this when I first started because it takes all the guess work out. No more wondering if I'm in Ketosis or not. So simple to use, just breathe into the device and you get a reading. I recommend this to anyone doing the Keto Diet or Low carb diet. You will thank me later!"
"After using this ketone measuring meter for the last few weeks, I can truthfully state that it is extremely easy to use, displays accurate information (I compared it to the prick system I own as well) and it's so convenient (it comes with a little case) because it's so small that it fits right in my purse and I can take it with me wherever I go! I highly recommend this meter if you're not a fan of drawing blood to read your ketones and you want a small contraption that fits in your purse or pocket!"

This breath meter is excellent I’m using it daily, it’s keeping me on track, and I can adjust what I eat to my results, quick delivery to NZ and very good communication, I see the KETOSCAN mini being in my kit on my keto journey for a long time thanks 😁
KetoScan Mini Ketone Breath Meter
The Ketoscan Mini is very easy to use and helps me stay disciplined with my diet so I can reach my target weight. I use it religiously everyday and pinpoints the days where my diet has an adverse and a positive effect on ketosis. If you are serious about a keto diet and lifestyle then you cannot do it without measuring your progress with relevant metrics … Ketsocan Mini allows me to do this. Thanks so much for an awesome tool.
The Ketoscan Mini is key to fine tuning my diet to make sure I am in ketosis. I can monitor my macro intake and to get the optimal balance. It has been revolutionary for me. It is easy to use, reliable and a good way to record notes on my diet.
Good product, with the compact size which I like. The only thing is you need to blow once to analyse the device and get it work before it get the real blow,kind of annoying. Otherwise all good and effective
KetoScan Mini Ketone Breath Meter
I am not shore how accurate it is I fast 24hours and have 1 meal and I never get past 10
Very happy
Very prompt delivery and the item is professionally packaged and connects easily to other devises via Bluetooth - I have had varying readings sometime within minutes of each usage - so I question its accuracy so I'm not 100% confident on the results - will continue to monitor and will test against urine strips for ketosis
This ketone monitor is heavily integrated with smartphones, but if you don't use one, while it still works, it is a bit primitive. That said, it's very simple to use and gives consistent readings. As for accuracy, that would need to be calibrated against blood tests, so I can't comment.
