ALCOSIM™ Breath alcohol simulator

ALCOLOCK is committed to offering top-quality products that we develop ourselves. We aren’t satisfied with offering a single device or reselling an existing line of products. Instead, we are committed to immersing ourselves in the industry. Over the years, we’ve grown to become recognized experts in our field. We remain at the top of the industry by developing best-in-class products that span the entire gamut, from lab equipment to devices that aid program facilitators to the breathalyzers and products the consumer uses throughout their program. ALCOSIM is one of the quality products we offer to help make the road to license reinstatement and independence as easy as possible for everyone involved.


Our ALCOSIM breath alcohol simulator paired with Alcohol Reference Solution (ARS) is used to calibrate various breathalyzers and ignition interlock devices. The ALCOSIM breath alcohol simulator effectively calibrates the sensor, ensuring the prolonged accuracy and longevity of your breathalyzer and ignition interlock device. Our ALCOSIM simulator generates a breath sample similar to a human’s to provide a precise calibration standard for your devices. To ensure the accuracy of calibration, the ALCOSIM maintains the temperature of Alcohol Reference Solution (ARS) at 34 ºC ± 0.02 ºC.
