The range

Two devices. One standard of accuracy.

Everyday Tester

Pocket-sized, ready in seconds

Everyday Tester

A compact, semiconductor-sensor breathalyser for quick personal checks before you decide whether to drive. Small enough for a glovebox or bag.

Precision Tester

Fuel-cell accuracy for regular use

Precision Tester

A fuel-cell sensor gives lab-grade accuracy and repeatable readings over thousands of tests — the option to reach for if you're testing often.

Aftercare

Sensors drift. Calibration corrects it.

Send your device in and we'll recalibrate it against a certified reference, so your readings stay accurate for years, not just out of the box.
