**Ketone Breath Testing** Ketone breath testing is a far more accurate and convenient method than urine strip testing. You only need to breathe into the digital ketone breathalyzer. This saves you from finger pricks, and the device can be used thousands of times. Comparatively, you can save money compared to using testing strips. This portable ketone breath tester is designed to be carried around anywhere in your pocket, ensuring you are in ketosis at all times. The ketone breath meter has three LED indicators: Green (Ketosis Reading Successful), Amber (Low Battery), and Red (Ketosis Reading Unsuccessful). The ketone breath monitor is easy to use with a one-button operation to get ketone readings. A reading of 0.0 signifies you are not yet in ketosis, while readings between 0.5 and 3.0 indicate you are in full ketosis, which is the optimal ketone zone. More reading details can be found on the detailed product page.
