The ketone breath test is a more accurate method than the urine strip test and offers convenient testing with a digital ketone breath analyzer. Avoid finger pricks by simply breathing into the device, which can be reused thousands of times, helping save money compared to disposable test strips. This portable ketone breath tester fits easily in your pocket and helps monitor ketosis levels anytime, anywhere. The ketone respirometer features three LED indicators: green for a successful ketosis reading, amber for low battery, and red for a failed reading. The breath monitor is easy to use with one-button operation. Ketone readings are interpreted as follows: a reading of 0.0 indicates you are not in ketosis, while a reading between 0.5 and 3.0 indicates you are in full ketosis, within the optimal ketone range. Additional reading details are available on the product description page.
