The ketone breath test is a more accurate method than the urine strip test. It is also more convenient as you only need to breathe into the digital tester, avoiding finger pricks. The device can be reused thousands of times, offering a cost-effective alternative to test strips. This portable ketone breath analyzer is designed to be carried anywhere in a pocket to help ensure you are always in ketosis. The ketone meter features three LED indications: Green for a successful ketosis reading, Amber for low battery, and Red for a failed reading. It is easy to use with one-button operation. A reading of 0.0 means you are not yet in ketosis, while a reading between 0.5 and 3.0 means you are in full ketosis, the optimal zone.
