SENTINEL™ Breath Alcohol Screening Entry System

The SENTINEL alcohol screening system enables high-volume "zero tolerance" screening of employees, contractors and visitors in safety sensitive industries such as Mining, Construction and Oil and Gas. The SENTINEL can significantly reduce industrial accidents linked to alcohol consumption.

The SENTINEL entry-point breath alcohol testing system is fast, totally automated and completely non-invasive. Tests are triggered automatically when the subject blows. No mouthpieces or straws are required. The SENTINEL uses internationally recognizable color icons to prompt subjects to blow and to display test results. There are no buttons to push or lights to interpret.

Like its predecessor, the SENTINEL Vehicular Access or SENTINEL-VA is a non-invasive system, and can be self-administered. A driver simply pulls up to the access point, takes the breathalyzer off of the cradle, blows into the instrument and is either allowed or denied entry based on the breath alcohol results. Alternatively, security personnel may hold or pass the breathalyzer to the driver. The SENTINEL-VA may also be used in place of the original SENTINEL to accommodate those employees who use wheelchairs.

Unlike other devices, screening results are delivered virtually instantaneously. Negative test results are delivered in less than 2 seconds ensuring access points do not become backed-up. Positive alcohol results are delivered in less than 10 seconds.

  • Interoperability - Designed to work as a stand-alone unit or integrated with existing time clocks, gates and other security controlled access points.**
  • Automatic Passive Testing - The test is automatically triggered as the subject blows towards the designated port. No mouthpieces or straws required. Low cost per test. Perfect for high volume environments.
  • Rapid Repeatability - Instant response on negative tests. Capable of taking hundreds of tests per day.
  • Icon Driven Communication - Universal, easy to understand visual prompts clearly communicate with the subject. No user interpretation needed.
  • Remote Updating - System is field upgradable using the internal USB interface
  • Serviceability - Calibrate the unit without removing the breathalyzer. Contains modular components for easy in-field replacements.
  • Platinum Fuel Cell Sensor - Provides exceptional accuracy as well as a long life span.
  • Adjustable Alcohol Levels - Easily adjust alcohol cut-off levels depending on your testing protocol. Choose from .000 BAC when any amount of alcohol is a violation, .02, .04, or any desired alcohol level.
