Quality engineering

Work environments are demanding.

ALCOLOCK V3 alcohol interlocks are engineered to withstand the vibration, dirt, dust, humidity and extreme temperatures typically found in commercial applications. They can be installed in any motorized equipment, including trucks, ships, trains and heavy machinery.

Simple breath sampling

Drivers use the handset to provide a breath sample. Within seconds the ALCOLOCK V3 device analyses it for breath alcohol content (BrAC) and displays instructions to the driver. Sensors help ensure mechanical devices such as air pumps cannot be used to circumvent the system.

 Programmable to suit your business

Drivers may be tested at the beginning of their shift, or at intervals throughout the day, by programming the ALCOLOCK V3 system to meet company safety policy requirements. Proprietary software allows reporting of logged events such as breath test results, times, dates and more.
