## Long description

The Riff RF-0078 High Accuracy Digital Rechargeable Breathalyzer with Professional Sensor and Sound Alarm is a compact, rechargeable personal breath alcohol tester designed for quick, on-the-spot checks. The unit uses a semiconductor sensor and a black-and-white LCD to display blood alcohol concentration (BAC) and breath alcohol concentration (BrAC) within the measuring range of 0.00–0.19% BAC (0–1.9 g/l). Housed in a PC plastic shell, the device combines a small lightweight form factor with a built-in 3.7 V 200 mAh polymer lithium battery for convenient travel and everyday monitoring.
Advantages
The breathalyzer provides fast measurements with a typical measuring cycle of 20 seconds and a warm-up time of approximately 10 seconds. Its semiconductor sensor together with a clear LCD numeric readout ensures easy interpretation of results. The integrated rechargeable battery supports about 150 continuous tests per full charge and the supplied charger conforms to DC 5V 1A requirements. Low standby current and compact dimensions make the device easy to store and transport while a sound alarm notifies when threshold values are detected.
Suitable for
 Personal monitoring before driving or operating machinery
 Travel and on-the-go alcohol checks
 Basic workplace spot checks where a portable tester is acceptable
 Home use for individuals who want quick BAC/BrAC feedback

Usage recommendations
To maintain measurement accuracy, avoid eating, smoking or rinsing your mouth immediately prior to testing. Charge the breathalyzer with a DC 5V 1A adapter and store it within the specified operating temperature range. The package includes one breathalyzer and the required charger.
