Main highlights

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.

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.

Freundliche Erinnerung: Bitte vergleichen Sie die Testergebnisse nicht mit denen des herkömmlichen Messgeräts, da es sich um unterschiedliche Analysemethoden handelt. Unser Keton-Atemanalysegerät verfolgt das Aceton im Atem, was ein besseres Maß dafür ist, was Ihr Körper tatsächlich als Brennstoff verwendet, da Aceton in unserem Atem ein tatsächliches Nebenprodukt der Fettverbrennung ist
Dieses Keton-Atemmessgerät ist ein benutzerfreundliches Selbstüberwachungsgerät für Personen, die eine ketogene Ernährung verfolgen. Der Ketose-Atemtester erspart Ihnen Stiche in den Finger und kann durch Austausch des Mundstücks wiederholt verwendet werden. Das spart Ihnen Kosten für den Test und spart Ihnen den ständigen Kauf von Teststreifen. Außerdem ist es praktischer, da Sie nur 5 Sekunden lang mit dem Monitor atmen müssen.
Das Atemketosemessgerät misst sechs Ketonwerte bis zu 99 ppm (0,0–99 ppm) in PPM (Parts Per Million). Die LCD-Anzeige verfügt über vier Farben: 0,0–1,9 Messwerte in WEISS, 2,0–39 Messwerte in GRÜN, 40–59 Messwerte in GELB und über 60 Messwerte in ROT. Der Ketose-Atemtester verfügt über 32 Speicherplätze zur Ketose-Aufzeichnung und wird mit zwei AAA-Batterien betrieben (nicht im Lieferumfang enthalten, aber handelsüblich).
Das Atemketonmessgerät erkennt Ihren Atemaceton von 0 bis 99 ppm und folgt 6 Stufenrichtlinien: 0,0–2 ppm (keine Ketose), 3–4 ppm (Ketose im Frühstadium), 5–10 ppm (leichte Ketose), 11–39 ppm (stabile Fettverbrennungszone), 40–59 ppm (Vorsicht – hohe Ketose), 60–99 ppm (Ketoazidose); Die Verfolgung des Atemacetons ist ein besserer Maßstab dafür, was Ihr Körper tatsächlich als Brennstoff verwendet, da Aceton in unserem Atem ein tatsächliches Nebenprodukt der Fettverbrennung ist.
