Important to Get Accurate Ketones Readings! The ketone breath meter needs to be exhausted before your first use since it may have residuals from production to warehouse; if you want to test another person consequently after your testing, please also kindly exhaust your previous residuals. To do so, please repeat the warm-up procedure 1-2 times (without blowing) before you proceed to your first test. During testing, please blow immediately within first 5-6 seconds when displaying "blo" on the ketosis tester since the keto breath tester starts analyzing the breath right after the first 5-6 seconds. Cautions Before Measurement: Please test your ketone levels under the same conditions each time right after waking up in the morning before consuming anything in fasting status! Using Steps: ✓ 1.Powered by 2x AAA alkaline batteries (not included) ✓ 2.Press the power button for 3 seconds to start device ✓ 3.Warm-up and exhaust residuals ✓ 4.Blow for 5-6 seconds right after warm-up ✓ 5.Ketone meter analyzes and reading shows ✓ 6.No more painful finger pricks or messy urine strips Breath Acetone Concentration Readings Instructions (PPM): Breath Acetone Concentration (ppm): 0 ~ 2 You are not in ketosis or just right before ketosis. Breath Acetone Concentration (ppm): 3 ~ 4 You are at very early stage of ketosis. Breath Acetone Concentration (ppm): 5 ~ 10 You are in a light status of ketosis. The body fat is burning at a low pace. Breath Acetone Concentration (ppm): 11 ~ 39 You are in the optimum level of ketosis. This is the stable fat burning zone, the process of fat being used by the body as the main source of energy. Breath Acetone Concentration (ppm): 40 ~ 59 Be Caution! You are approaching too much ketosis level. Adjust your level to under 40ppm. Breath Acetone Concentration (ppm): 60 ~ 99 Danger! You are in too high level of ketosis. Ketoacidosis.

Cautions before measurement: Be cautious about factors that may affect your results because the device is with high sensitivity sensor and avoid brushing your teeth, smoking, drinking or eating foods 30minutes before taking the test for accurate results. In order to accurately analyze and track your testing readings, we strongly recommend testing your ketone levels under the same conditions each time right after waking up in the morning before consuming anything in fasting status. Breath ketone meter detects your breath acetone from 0 to 99 PPM and follow 6 level guidance: 0-2ppm (No ketosis), 3-4ppm (Early Stage Ketosis), 5-10ppm (Light Ketosis), 11-39ppm (Stable Fat Burning Zone), 40-59ppm (Caution-High Ketosis), 60-99ppm (Ketoacidosis); Tracking breath acetone is a better measure of what your body is actually using for fuel because acetone in our breath is an actual byproduct of fat burning, and 80% of fat that we burn leaves the body through the lungs. Breath ketone meter measures 6 levels of ketones up to 99 PPM (0.0 -99), using a PPM (Part Per Million) measurement. Ketone breath meter with 3 LED indications: Green Light (Ketosis Reading Successfully), Amber Light (Low Battery), Red Light (Ketosis Reading Unsuccessfully); the keto tester device powered by 2*AA batteries (not included but commonly available). This ketone breath analyzer is an easy-using and self-monitoring device for individuals following on a keto life. Ketosis breath tester saves you from finger pricks, and the device can be used repeatedly by replacing the mouthpiece, which saves your money for testing from continiously buying strips, also more convenient because you only need to breathe with the monitor for 5-6 seconds. The ketosis breath tester needs to be exhausted before your first use. To do this, turn on the ketone breath meter, wait for the 20 seconds countdown to be completed, and turn it off. Repeat the same procedure 1-2 times (without blowing) before you proceed to your first test. During testing, please blow immediately within first 5-6 seconds when displaying "blo" on the ketosis tester, since the ketone breath tester starts analyzing the breath right after the first 6 seconds.
