This device is intended to measure alcohol in human breath. Measurements obtained by this device are used in the diagnosis of alcohol intoxication.

The AlcoHAWK® PT500 is designed to measure deep lung air to test for the presence of alcohol in the blood. The relationship between alcohol in the blood and alcohol in the deep lung breath is well established by Henry's law in ratio of 2100:1 The AlcoHAWK® PT500 has been tested and uses a blow time of 5 seconds to capture an accurate deep lung sample. The AlcoHAWK® PT500 sensor uses a fuel cell type of detector similar to one found on professional units. It is handheld and uses two AA alkaline batteries as a power source. The mouthpiece is replaceable Plexiglas plastic.

The Alcohawk Precision™ is designed to measure deep lung air to test for the presence of alcohol in the blood. The relationship between alcohol in the blood and alcohol in the deep lung breath is well established by Henry's law in ratio of 2100:1 The Alcohawk Precision™ is a D.O.T. approved alcohol screening device and uses a blow time of 5 seconds to capture an accurate deep lung sample. The Alcohawk Precision™ contains a semiconductor oxide sensor designed to test for the presence of alcohol. Gas sensitive semiconductor material is formed on an alumina substrate on which the gold electrodes are printed. A thick film heater of ruthenium oxide is printed on the reverse of the substrate and placed in the plastic housing. The tin dioxide (SnO2) metal oxide semiconductor material is heated to a specific temperature. The resistance of sensing material changes rapidly according to gas concentration changes, thereby enabling the reading of alcohol concentration by resistance measurement.
