What is the precision of KETOSCAN Mini?

Relationship between blood acetone concentration and acetone concentration of breath matches 100%. Therefore, KETOSCAN Mini can precisely
measure blood acetone concentration. Sentech GMI Corp. uses respiration gas analysis technology of the mother company, Sentech Korea Corp.,
which has 20 years of breathalyzer technology, to guarantee the precision of KETOSCAN, and it is a global product with US FDA approval for the
safe use.

What is a self-diagnosis mode?

KETOSCAN uses a self-diagnosis function, which is a patented technology. If the equipment is not used for a while and left alone, even if it is a small
amount, gas around the house enters inside the unit, changing the baseline of the sensor and may affect to the test result. KETOSCAN has patented
technology that can self check the equipment status during the measurement preparation stage, and if it decides that the baseline is incorrect, it does
not show the result after blowing but uses respiration gas for the baseline adjustment and requires the measurement again. Self-diagnosis operates
automatically as such according to the situation, so even if it occurs frequently, it is not that the malfunctioning but it is for the more precise
measurement, so you don’t have to worry about it.

What is a sensor replacement?

As explained above, to measure acetone gas, it needs to detect extremely low concentration of ppm level, so high sensitive sensor is required. If you
use sensor frequently, it is inevitably contaminated by other gases mixed in the breath, which requires readjustment of the precision, and such process
is called calibration. But, only with calibration, the sensor cannot be fully recovered, so KETOSCAN requires sensor replacement service. The mobile
App. KETOSCAN displays the message recommending sensor replacement after 300 times usage and stops the use of the equipment at 320 times
measurements, so you need to request sensor replacement service to the closest local service center.
