Literally translated, transdermal means “transfer through the skin”. SCRAM measures
insensible perspiration, which is the constant, unnoticeable excretion of sweat through the
skin. The average person emits approximately one liter of insensible perspiration each
day. SCRAM measures the ethanol gas in this insensible perspiration, which is a
predictable result of alcohol consumption. The SCRAM Bracelet takes this measurement
by pulling a sample of air from the area above the skin into a chamber with an
electrochemical sensor.
Transdermal Alcohol Concentration, (TAC) readings are based on a long-standing,
industry accepted, scientific foundation and can be correlated to Blood Alcohol
Concentration (BAC) readings.
Transdermal alcohol testing using the bracelet is passive and done automatically
according to a pre-determined schedule. The need for clients to travel to a testing center
is eliminated as each reading is date and time stamped and stored in a memory chip
within the bracelet. The agency can set up and modify the testing schedule based on the
needs of the client.
