AlcoHAWK Precision/Elite/PT500 Professional Mouthpiece (100 pack)

100 individually wrapped mouthpieces for use with the AlcoHAWK Precision, AlcoHAWK Elite, or AlcoHAWK PT500. Professional mouthpiece limits saliva and foreign material for entering the unit. This helps extend sensor life. It also features one direction flow which prevents the user from inhaling (suck back) though the unit in an attempt to manipulate results.
