Suresign 2 Alcohol Screening Tests

Suresign 2 Alcohol Screening Tests to take before driving, operating machinery or doing dangerous jobs. The breath alcohol detector is for rapid detection of the presence of alcohol in the exhaled breath and provides relative Blood Alcohol Concentration (BAC) at 0.05%. The test is based on a chemically chromogenic reaction. Alcohol, if present in the exhaled breath, reacts with the chemically coated crystals and produces a colour change. This colour change is proportional to the concentration of alcohol in the breath, which is an approximation of relative Blood Alcohol Concentration (BAC).
