Professional Breath Alcohol Sensor

This breath alcohol sensor is intended for professional applications or removable interlock devices (type 3 only).

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.

The sensor is available with pins or bare wires for soldered applications.
NOTE: The connection pins are intended to be solderless. A matching socket part number is available, or spring clips can be used

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