OEM72 CO2 - Carbon Dioxide Analyser

Carbon Dioxide Analyser CO2 Analyzer consists of a panel mount display unit and a separate sensor that is installed remotely


A Carbon Dioxide analyser in modular form, which consists of a panel mount display unit and a separate sensor that is installed remotely.

This unit is intended to be integrated into a control panel and is supplied in component form. It will require some wiring between the display and sensor and additional components such as a flow-meter and power and mute switches.

A separate flow-meter and metering valve is required as the sensor is designed for use in sampled gas systems. The sensor housing can also accommodate an O2 sensor and flow adaptor, which will connect to its own companion OEM72 display. This is ideal for limited space applications where oxygen and carbon dioxide analysis is required.

The OEM72 display has high and low set points with an audio visual alarm and mute circuit.

Day to day calibration is carried out via the front panel keypad. All the calibration and alarm parameters are retained in non-volatile memory.
