Alcohol interlock is a device that prevents an intoxicated person from driving a vehicle. It is easy to understand how it works. System will enable vehicle to be started only after driver has provided an air sample with zero alcohol content. Otherwise, alcohol lock circuit will remain locked and vehicle cannot be started. Alcohol interlock is equipped with a platinum electrochemical sensor and a heater, which allows short activation time and accurate measurement at any time of year. Device has a built-in data memory that stores up to 65,000 events.
