Präzision und Genauigkeit: Der Keton-Atemtester kann die Ketonwerte in Ihrem Atem präzise messen. Er verwendet fortschrittliche Halbleitersensoren, um zuverlässige Daten zu liefern und Ihnen dabei zu helfen, Ihren Ketosestatus zu überwachen. Der Keton-Atemtester ist kalibriert, um die Acetonkonzentration zu erkennen und sicherzustellen, dass Sie konsistente und genaue Ergebnisse erhalten, was für Personen, die eine ketogene Diät einhalten, äußerst effektiv ist.
Dieser Ketose-Atemtester ist ein einfach zu verwendendes und selbstüberwachendes Gerät für Personen, die eine ketogene Ernährung verfolgen. Der Ketose-Atemtester erspart Ihnen Stiche in den Finger und das Gerät kann durch Austauschen des Mundstücks wiederholt verwendet werden, wodurch Sie Geld für den Test sparen, da Sie keine Teststreifen mehr kaufen müssen. Außerdem ist es praktischer, da Sie nur 5 Sekunden lang mit dem Monitor atmen müssen.
Der Ketose-Atemtester misst 6 Ketonwerte bis zu 99 PPM (0,0 - 99) mithilfe einer PPM-Messung (Parts Per Million). Keton-Atemtester mit 3 LED-Anzeigen: Grünes Licht (Ketosemessung erfolgreich), gelbes Licht (Batterie schwach), rotes Licht (Ketosemessung fehlgeschlagen); das Ketotestgerät wird mit 2 AA-Batterien betrieben (nicht im Lieferumfang enthalten, aber allgemein erhältlich)
Der Keton-Atemtester muss vor der ersten Verwendung entleert werden. Schalten Sie dazu den Keton-Atemtester ein, warten Sie, bis der Countdown von 20 Sekunden abgelaufen ist, und schalten Sie ihn aus. Wiederholen Sie den Vorgang 1-2 Mal (ohne zu pusten), bevor Sie mit Ihrem ersten Test fortfahren. Während des Tests pusten Sie bitte 5-6 Sekunden lang, sobald „START“ angezeigt wird. Dann beginnt der Keton-Atemtester mit der Analyse Ihres Atems. Die Ergebnisse sind 10 Sekunden lang sichtbar.
Bitte beachten Sie: Es gibt eine Zeitverzögerung, bevor Ihr Ketonspiegel nach dem Verzehr von kohlenhydratreichen Lebensmitteln sinkt, weshalb Sie danach möglicherweise immer noch hohe Werte erhalten. Die Zeitspanne ist bei jedem Menschen unterschiedlich und hängt auch davon ab, wie lange Sie bereits ketogen leben.

In order to always be able to safely detect whether you are optimally in ketosis, you can use our ketone meter and regularly check your congestion.

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.

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.

Osis), 60-99 ppm (ketoacidosis); Acetone 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
