The AlcoHAWK PT500 is the newest unit in the AlcoHAWK Series line of breath alcohol testers. It incorporates our PT Core fuel-cell sensor, which is not subject to interference from acetone and offers enhanced linear accuracy over traditional semi-conductor sensors. The simple menu-driven operation allows you to quickly and accurately screen for the presence of alcohol up to 0.400 percent BAC. The AlcoHAWK PT500 also features a large, easy-to-read back-lit LCD display. The AlcoHAWK PT500 is the ideal unit for law enforcement roadside screening, corrections, probation officers, substance abuse clinics, boating, military, and many other areas of professional testing in which fuel-cell accuracy and reliability is required. And because the PT500 now has obtained FDA 510K Premarket Clearance, it is also available for consumers to purchase. The AlcoHAWK PT500 is a DOT / NHTSA Conforming Breath Alcohol Screener.
