DD Scientific GS+4CO-HC Carbon Monoxide Gas Sensor, Sensor Only

GS+4CO-HC (also written GS+4COHC or GS4COHC) is a DD Scientific electrochemical carbon monoxide sensing component for high-concentration applications. This listing is for the sensor, not a complete gas detector or smoke/fire alarm.

Model reference specifications

• Target gas: carbon monoxide (CO).
• Interface: 4-Series, 3-pin sensor; 0 V bias.
• Manufacturer reference range: 0-10,000 ppm.
• Output: 20 +/- 10 nA/ppm; T90 response time: less than 40 seconds.

These model specifications require the manufacturer's recommended sensing circuitry and test conditions. The sensor is not a standalone 3.3 V or 5 V detector module.

Check before replacing another sensor

Compatibility with Alphasense CO-AE is not confirmed. Match the equipment's specified sensor, pin functions, bias and signal requirements; a similar size or gas range does not establish interchangeability. Installation, calibration and response testing must follow the equipment manufacturer's instructions before use.
