SCRAM Alcohol Monitor
How SCRAM CAM Tests Alcohol Through the Skin”
When someone drinks alcohol, much of it is absorbed and metabolized in the body, but about 4% of it is excreted through the lungs and kidneys, and 1% through the skin in the form of insensible perspiration. SCRAM CAM tests that insensible perspiration using an electrochemical fuel cell by sampling the wearer’s sweat every 30 minutes.
