Breath Alcohol Sensor

This 11mm Breath Alcohol Sensor range is suitable for consumer applications. This product is appropriate for frequent use or where a positive result is likely.

Dart Sensors breath alcohol sensors are of the two-electrode electrochemical type, requiring a pumped sample of air to be delivered into either tube. In the presence of ethanol vapour a small direct current is produced; the breath alcohol sensor requires no power supply of its own but this current requires amplification to make it readable using external data collection equipment.

• Type 5 is for replacements in legacy applications only.
• Type 4A is the standard formulation for normal humidity and temperature.
• Type 3A is suitable for use where resistance to extreme climatic conditions is required.

See the datasheet for more information.

Each sensor is laser marked with serial number. Test data available on request.
