The TEC CO is a device for monitoring very low levels of carbon monoxide (CO). This is housed in a robust miniature enclosure rated for IP55 ingress protection, with built-in temperature compensation and an RS485 digital output via Analox communications protocol. The sensors are backwards-compatible with the existing MEC (mini electrochemical) range and offer the same modular approach to gas monitoring.

Carbon Monoxide Sensor
The TEC CO sensor was developed with signal stability in mind. It uses a sophisticated 4-pin electrochemical sensor which provides greater sensitivity than a 3-pin type, and its ‘plug-in’ mounting ensures that the cell pins have very short tracks to the circuit board for improved noise immunity. This connection arrangement not only maximizes sensor performance but also simplifies routine maintenance such as cell replacement.
