This ketosis breath tester is an easy to use and self-monitoring device for people who follow a ketogenic diet. The ketosis breath tester saves you stitches in the finger and the device can be used repeatedly by replacing the mouthpiece, saving you money on the test as you no longer have to buy test strips. It is also more practical as you only need to breathe with the monitor for 5 seconds.
The ketosis breath tester measures 6 ketone values up to 99 PPM (0.0 - 99) using a PPM measurement (Parts Per Million). Ketone breath tester with 3 LED indicators: green light (ketosis measurement successful), yellow light (battery low), red light (ketosis measurement failed); the keto tester is powered by 2 AA batteries (not included but generally available)
The ketone breath tester must be emptied before first use. To do this, turn on the ketone breath tester, wait for the countdown of 20 seconds to expire and turn it off. Repeat the process 1-2 times (without blowing) before proceeding with your first test. During the test, please blow for 5-6 seconds once "START" is displayed. Then the ketone breath tester starts analyzing your breath. Results are visible for 10 seconds.
Precision and Accuracy The ketone breath tester can accurately measure the ketone levels in your breath. It uses advanced semiconductor sensors to provide reliable data and help you monitor your ketosis status. The ketone breath tester is calibrated to detect acetone concentration and ensure you get consistent and accurate results, which is extremely effective for people following a ketogenic diet.
Please note: there is a time delay before your ketone levels drop after eating carbohydrate-rich foods, which is why you may still get high levels afterwards. The time span is different for each person and also depends on how long you have already lived ketogenically.

This ketone breathing meter is a user-friendly self-monitoring device for people who follow a ketogenic diet. The ketosis breath tester saves you stitches in the finger and can be used repeatedly by replacing the mouthpiece. This saves you costs for the test and saves you the constant purchase of test strips. It is also more practical as you only need to breathe with the monitor for 5 seconds.
The respiratory ketosis meter measures six ketone values up to 99 ppm (0.0-99 ppm) in PPM (Parts Per Million). The LCD display has four colours: 0.0-1.9 readings in white, 2.0-39 readings in green, 40-59 readings in yellow and over 60 readings in red. The ketosis breath tester has 32 memory slots for ketosis recording and is powered by two AAA batteries (not included but commercial).
The respiratory ketone meter detects your breathing acetone from 0 to 99 ppm and follows 6 level guidelines: 0.0-2 ppm (no ketosis), 3-4 ppm (early stage ketosis), 5-10 ppm (light ketosis), 11-39 ppm (stable fat burning zone), 40-59 Ccaucaucaucaucaucau– high ketosis), 60-99 ppm (ketoacidosis); tracking breathing acetone is a better measure of what your body actually uses as fuel, as acetone in our breath is an actual by-product of fat burning.
Friendly reminder: please do not compare the test results with those of the conventional meter as it is different analysis methods. Our ketone breath analyzer tracks the acetone in the breath, which is a better measure of what your body actually uses as fuel, as acetone in our breath is an actual by-product of fat burning
