Intoximeters, Inc. is a privately held company headquartered in St. Louis, Missouri USA and with a satellite office in Totnes, Devon UK. Intoximeters produces and markets a full line of alcohol breath testing instruments for screening and evidential applications worldwide. Since 1945 Intoximeters has been a leader in the breath alcohol detection field. Early on, law enforcement, probations and correction agencies were the primary customers for this type of equipment. However, as the extent of alcohol abuse in society became more recognized, other markets for breath alcohol testing products developed - most notably in the industrial occupational health sector.
