Having an accurate, reliable monitor means that you should always be kept safe when working with or around carbon monoxide (CO).

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.
The TEC CO sensor is intended for use as a sub-component in larger systems designed to monitor carbon monoxide gas at accuracies of parts per billion (sub-ppm level). Typical applications include medical air facilities, atmospheric pollution monitors, breathing air compressors and saturation/commercial diving systems. 
The TEC CO sensor can be installed either in the open environment or directly in the gas path.
The TEC CO sensor can be supplied as an original equipment manufacturer (OEM) component for third party systems integration. It can also be incorporated in Analox products such as the SDA CO+ or the ACG+, built specifically for applications measuring sub-ppm gas values.
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.
