AlcoSense Pro

SKU: ALS-PRO Category:


The AlcoSense Pro Breathalyser was the first semiconductor breathalyser certified to Australian Standard AS3547. It uses advanced semiconductor technology that is accurate and cost-effective.

The AlcoSense Pro can be operated in two modes. Normal mode measures a specific blood alcohol concentration. Alternatively it can be used as an alcohol responder (shared between multiple people) to test the presence of alcohol.

An Automatic counter shows the number of times the unit has been used, and advanced error check technology also ensures accurate results with every use.
