Drager Tubes CH199 - .08‰ B.A.C.
Drager Tubes CH222 - .05‰ B.A.C.
Testing for alcohol with Drager tubes is efficient and inexpensive. Alcohol testing equipment may be too impractical to take into the field, so that is when Drager Alcotest Tubes are perfect for mobile alcohol testing. These tubes are quick to use and give immediate results for traffic safety use, correctional facilities and industrial use. When testing for alcohol, it is recommended that the test is given at least fifteen minutes after the last drink is consumed. Immediately after consumption of alcohol, a high alcohol content is present in the mucous membranes of the mouth and throat. This mouth alcohol level would provide a false alcohol level if testing is done within fifteen minutes of consumption.
To perform the test for alcohol with the Drager tubes, the tips of the tube are opened and the tube is connected to the the breathing bag. The person being tested exhales into the tube and inflates the bag. If alcohol vapor is present in the exhaled breath, the yellow indication layer turns green.
