Patented Deep Lung Sampling technology measures breath acetone levels from only the latter part of the exhalation to gain the most accurate breath acetone detection.
Its sleek design fits in the palm of your hand.
Battery life depends upon the preparation time, the number of measurements you make each day and the standby time (how long your device is asleep between each measurement.) From fully charged, and testing between 1-5 measurements each day, your battery should last 2-4 days between charges.Note that your Biosense device runs additional sensor diagnostics when asleep and plugged in to the charger. Plugging your device in each night, or every few nights, will therefore help reduce preparation time for measurements and maintain accuracy.
The Biosense® device uses patented Deep Lung Sampling technology to perform breath acetone measurements. The consistent sampling of only the latter part of the exhalation enables the most accurate level of breath acetone detection for nutritional ketosis monitoring. Deep lung sampling provides accurate and reproducible measurements by correcting for natural variations in exhalation time and lung capacity across individuals. Biosense® is the only breath monitor to provide this patented technology.

"Our patients are having insane success with Biosense®...
-44 lb weight loss in three months
-Insulin-resistant score 93 >> 5
That's amazing. Plenty of these types."
*Two extra mouthpieces
While your device comes equipped with a mouthpiece, you can order 2 additional ones here in case you want to replace them if they get lost, or you would like to use new ones for hygienic reasons.
