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.

The ketone breath analyzer of measurement for respiratory ketone analyzer is (PPM). When the body enters a state of ketosis, it produces ketones, which are by-products of fat metabolism. As the body produces more ketones, it produces ketones, which are by-products of fat metabolism. As the body produces more ketones, the concentration of acetone in the breath also increases
The ketone breath analyzer must be exhausted before first use. To do this, turn on the keto breath meter, wait for the 15 second countdown to complete and turn it off. Repeat the same process 1-2 times (without bubbles) before proceeding with your first test. During the test, please blow immediately for 5-6 seconds, once "Start" is displayed, then the ketone breath analyzer will start analyzing your breath
Respiratory ketone analyzers can measure acetone concentrations from 0 to 99 ppm, using a six-step scale: 0-2 (no ketosis), 3-4 (early ketosis), 5-10 (light ketosis), 11-39 (stable fat burning zone), 40-59 (high ketosis). 60-99 (Ketoacidosis). Acetone more accurately reflects the actual fuel consumption of the body, as exhaled acetone is a real by-product of fat burning and 80% of the burned fat is excreted through the lungs.
How long does it take to get into ketosis? This is not possible within 24 hours. Your body burns sugar for a lifetime as an energy source. The switch to burning ketone bodies takes time; this transition can take between 48 hours and a week. The time required depends on your activity level, lifestyle, body type and carbohydrate intake. Use a ketone meter to monitor your ketone levels; you just need to breathe in.
