The Alco-Sensor IV is a fool-proof alcohol detection device. Automatic features not on the Clinical Alco-Sensor or Alco-Sensor III give greater accuracy and reduce the chance of operator errors drastically. With a powerful computer chip stored inside, the Alco-Sensor IV can perform self-diagnostics. Specifically, when in use, the LED display lets the tester know if the breath sample is adequate for testing. Inadequate breath samples return a "NoGo" display on the LED letting the user know to try again. Each result is temporarily stored in memory and current tests can be re-displayed using the recall button.
The Alco-Sensor IV comes with a one year warranty.
