Regular price $279.00


KetoScan Ketone Meter

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.

3-Second Breath Ketone Analyser

To use the KetoScan, simply take a breath, then breathe out into the device. The result is displayed after blowing into the ketone breath analyser for just 3 seconds. The KetoScan's highly sensitive flow-rate sensor ensures accurate results.

Highly Sensitive Ketone Sensor

The highly precise acetone sensor of the KetoScan Mini is unique to other breath sensors in that it is 10 times more sensitive to ethanol, and 50 times more sensitive to hydrogen (generated in the intestines) than other sensors are. It is designed to detect acetone, and ignore other gasses that could contaminate the results.

KetoScan Ketone Meter

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!

Measures Up To 99 PPM

The KetoScan accurately measures breath acetone concentration at 100 resolutions (0.0~99) using a PPM (Part Per Million) measurement. It 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.


Smart Self-Diagnosis

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.


KetoScan Mobile App

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.

Diet, Health and Ketone Monitor App

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.


Cautions Before Measurement

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 food 30 minutes before taking a ketone test for a more accurate breath acetone concentration.


How to Check Your Ketone Levels Easily

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.


Detects Your Breath Flow-Rate

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.


Email Your Ketone Test Results Easily

A Complete Ketone Test Kit for Anytime Use

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.

KetoScan Mini's Ketone Levels Chart

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.

KetoScan Maintenance / What is a Calibration?

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.

Each calibration will be $75. To get your device calibrated, register your Ketoscan and make a booking online on Andatech Caltrace.

How Often Should I Test Myself With the KetoScan?

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 set the best time of the day to test yourself and are looking to compare these results with a urine ketone test, it is best to conduct both tests at the same time of the day.

We recommend that testing once a day would be good enough. Note also that the unit gets locked and will require calibration after 320 tests, so if you test too often, you will need to send your unit back for calibration more frequently.

What is the KetoScan's Smart Self-Diagnosis Feature?

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. 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.


How Do I Replace the Disposable Mouthpieces? How Many Times Can I Use One Disposable Mouthpiece?

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.


Do I get different results on a ketone blood test versus a ketone breath test?

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 compared to blood testing.

If you have blood readings from 0.5 to 3.0 mMol, then the KetoScan Mini will display the earlier state for optimal level of ketosis with PPM resolutions. For the details of PPM level for each ketosis state, please check our ketones level chart guide under the Product Description.

What Are Ketones and Ketosis?

Ketones, also known as 'ketone bodies', are by-products 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 it effectively helps to burn fat for energy. However, when you have diabetes, you can build up too many ketones in your blood -- ketone levels that are too high can become life-threatening (a condition called ketoacidosis).


How Do You Measure Ketones?

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 meters – measures β-hydroxybutyrate through blood - the most accurate method available but very expensive.


What are Breath Ketones?

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.


Which Is the Best Ketone Meter Method?

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!

Measuring Ketones in Urine


  • Inexpensive.
  • Widely available.
  • Non-invasive.



  • Less accurate in measuring ketone production and breakdown.
  • Accuracy can further decrease when the body adapts to excreting fewer ketones in urine.
  • Does not quantify how "deep" you are in ketosis.

Measuring Ketones in Breath


  • Affordable.
  • Free once you purchase the device (no consummables such as test strips).
  • Non-invasive and convenient.



  • Less accurate than blood testing in measuring ketone production and breakdown.
  • Measures acetone, a metabolic waste product, providing readings that relate well only to low blood ketone levels (not suitable for diabetic users monitoring BHB levels).

Measuring Ketones in Blood


  • Most accurate way to measure ketosis in mmol/L (mM).
  • Measures BHB, the preominant ketone in the body, rather than acetoacetate or acetone.



  • Expensive to purchase and keep using (test strips).
  • Invasive - must provide finger prick blood sample for each ketone test.

Ketoscan Clinical Trial

Ketoscan Clinical Trial 1


KetoScan is a breath ketone meter that monitors your body fat burning rate. The creators behind KetoScan Mini 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:

  1. Accuracy of KetoScan Mini’s analysis of body fat burning rate in each level.
  2. Breath acetone level displayed by the KetoScan Mini when meal and exercise are combined.
  3. The use of KetoScan for checking fat metabolism..


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 Mini’s body fat burning measurement

| Measurement: 3 times/day (at the same time every day), Brac measured by KetoScan Mini, 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 grams 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 Mini’s pre-set value are about the same.


Ketoscan Clinical Trial 2


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:

  1. Breath acetone has a strong correlated with BOHB.
  2. KetoScan shows stable breath acetone concentration under ketosis state.
  3. From the KetoScan’s result, the average value of blood meter over the past few hours can be calculated.


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 previous scientific articles.

However, since the dispersion is large, it is difficult to present correct BOHB readings 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 meters (BOHB) decreases rapidly, KetoScan (acetone) has less variations 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 drop to 0.1mM which is considered out of ketosis?

  00:00 03:00 06:00 09:00 12:00 15:00 18:00


  1. If the body consumes BOHB rapidly for various reasons, such as exercise, the blood meter reading drops sharply and goes into an 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 will usually recover soon.

The reason why blood meter readings change so much, even though the 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.

Check out our correlation data between your acetone levels and BOHB values.

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.

Worth it for those new to Keto

Very happy

Paul D.
jury still out

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
