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.
