A high volume ‘zero tolerance’ alcohol screening breathalyser and access control solution from Lifeloc.

Easy to Integrate and Use
The Sentinel™ can stand alone or be sequenced with existing turnstiles, time clocks or other employee access control systems. Sentinel™ screening is completely non-invasive and self-administered. Test supervision is not required. Results are displayed in clear unambiguous internationally recognizable icons. Subject pre-qualification, instruction and test monitoring is not required.

Fast and Reliable – 2 seconds per test
Tests are triggered automatically when the subject blows on the collector cone and take less than 2 seconds to complete. Results are delivered instantly on “negative for alcohol” tests and in under 10 seconds on positives. The Sentinel™ can easily handle hundreds of tests per hour ensuring that pre-shift screening flows smoothly without bottlenecks and lost time.

No Consumables
Mouthpieces or straws are not required and there are no recurring monthly charges. Annual calibration is easily performed in-place by non-technical staff without removing the Sentinel™ from service. The anodized aluminum housing protects against dust, dirt and vibration found in heavy industry.
