Cheetah-1 Breathalyzer (Fuel Cell Sensor)

The Cheetah-1 breathalyzer is a compact handheld device designed for swift and reliable breath alcohol measurement. It leverages advanced fuel cell technology to enhance accuracy and dependability. Notably, the Cheetah-1 eliminates the need for mouthpieces, offering user-friendly convenience. Fuel cell sensors operate through an electrochemical process, where they oxidize alcohol in the breath sample. This oxidation generates an electrical current, which the breathalyzer detects and translates into a precise Blood Alcohol Concentration (BAC) reading. The strength of the current directly correlates to the alcohol volume in the sampled breath.



The Cheetah-1 breathalyzer is a handheld device designed for rapid breath alcohol assessment, and it boasts advanced fuel cell technology, guaranteeing heightened reliability. Unlike some other devices, the Cheetah-1 does not necessitate the use of mouthpieces.

Operating on the principles of electrochemical sensing, the fuel cell sensors facilitate an electrochemical process that oxidizes the alcohol present in a breath sample. This oxidation generates an electrical current, which the breathalyzer carefully gauges to calculate the Blood Alcohol Concentration (BAC). The strength of this current directly corresponds to the volume of alcohol detected in the sample.
