This ketosis breath tester is an easy to use and self-monitoring device for people who are on a ketogenic diet. The ketosis respirator saves you stitches in the finger and the device can be used repeatedly by replacing the mouthpiece, saving you money on tests as you don't need to buy test strips. It is also more practical because you only need to breathe for 5 seconds with the monitor.
The ketone breath tester must be emptied before first use. To do this, turn on the keto breathing meter, wait for the countdown of 20 seconds to expire and turn it off. Repeat the same process 1-2 times (without blowing) before proceeding with your first test. Blow for 5-6 seconds during the test as soon as "START" is displayed. Then the ketone breath tester starts analyzing your breath. Results are visible for 10 seconds.
The ketone breath tester measures 6 ketone levels up to 99 PPM (0.0 - 99) using a PPM measurement (Part Per Million). Ketone breath meter with 3 LED indicators: green light (ketosis measurement successful), yellow light (low battery), red light (ketosis measurement failed); the keto tester is powered by 2 AAA batteries (not included, but generally available).
Precision and Accuracy The ketone breath tester can accurately measure the ketone level in your breath. It uses advanced semiconductor sensors to provide reliable data and help you monitor your ketosis state. The ketone respirator 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 readings afterwards. The time delay is different for each person and also depends on how long you have already been on a ketogenic diet.

This ketone breath analyzer is an easy to use and self-monitoring device for people who live a ketogenic life. The breath ketosis meter saves you stitches in the finger and the device can be used repeatedly by replacing the mouthpiece, saving you money on tests as you don't need to buy test strips. It is also more practical as you only need to breathe with the monitor for 5 seconds.
The respiratory ketone meter detects your respiratory acetone content from 0 to 99 ppm and follows 6 step instructions: 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 ppm Caution – high ketosis), 60-99 ppm (ketoacidosis); Monitoring the acetone levels in the breath is a better measure of what your body actually uses as fuel, since acetone in our breath is an actual by-product of fat burning and 80% of the fat we burn leaves the body through the lungs.
The breath ketosis meter measures 6 ketone values up to 99 PPM (0-99) using a PPM (Part Per Million) measurement. 4 LCD display colours for displays: 0-1 readings with WHITE light, 2-39 readings with GREEN light, 40-59 readings with yellow light and over 60 readings with RED light. This ketosis breath tester has 32 memory records to record ketosis data and is powered by 2 AAA batteries (not included but generally available).
PRECAUTIONS BEFORE MEASUREMENT Be careful with factors that may affect your results as the device has a highly sensitive sensor, and avoid brushing, smoking, drinking or eating 30 minutes before performing the test to get accurate results. To accurately analyse and track your test results, we strongly recommend testing your ketone level every time immediately after waking up in the morning under the same conditions before taking anything in the fasting state
A ketone breathing meter is a portable device that measures the ketone level in the breath. This non-invasive device uses advanced sensor technology to determine acetone concentration in the breath, which is a reliable indicator of the body's ketone levels.
