This device uses the same technology as that used in hospitals and by law enforcement agencies. You can rely on the accurate and repeatable results to inform your decisions about driving. Accuracy is maintained over thousands of tests.
The built-in memory saves your last 10 readings in case you need to look back at them. The operation is simple and you can begin testing within seconds. A reassuring click tells you when enough breath has entered the alcohol sensor cell. In addition, there are a number of further features including a continuous check of temperature, warning levels that can be adjusted by the user and a mini-solenoid breath pump system.
