Alcohol Interlocks
Vehicle alcohol interlocks that prevent a vehicle from starting if the driver is above the legal limit, with a fuel cell sensor that ensures the result is defensible at audit or in dispute.

View specification →Where This Range Earns Its Place
Problems it solves
- Screening at the gate only proves the driver was sober at the gate, not at the time of driving
- Nobody is present at a remote yard at three in the morning to stop an impaired driver
- A vehicle that starts without a test can be driven by someone who has consumed alcohol after the gate check
- Interlocks with semiconductor sensors drift and produce unreliable results over time
- No record of who was tested and when is stored if the system does not log the event
Who Buys This Range
- Fleet operators requiring a hard stop before vehicle start
- Bus and coach companies enforcing alcohol policies on drivers
- Mining haulage contractors managing high-risk vehicle operations
- Monitoring programme operators running compliance checks across multiple sites
- Safety managers needing a defensible record of every test and vehicle start
Where It Gets Used
- Remote mine haul truck yard at 03:00 with no supervisor present
- Bus depot at shift start where every driver must pass a test before the vehicle is started
- Fleet management system requiring a digital record of each test and vehicle start
- Contractor site where vehicle access is restricted to drivers who pass a breath test
- Monitoring programme running random checks across a national fleet
What You Are Actually Paying For
- Fuel cell sensor responds only to ethanol, not to acetone, fuel vapour or tobacco smoke
- Accuracy of +/-0.005 percent BAC at 0.050 percent BAC at 25 C on the published specification
- Ready to test in approximately 1 second at 25 C, 120 seconds at -20 C, 180 seconds at -40 C
- Calibration interval stated as 12 months, not open-ended
- Operates on 9V or 36V DC, so the same unit works in cars and trucks
- Handset and control box linked over UART, with external communication via RS-485 and RS232
