The PureAire Multichannel Controller connects 2-wire or 3-wire to oxygen monitors, analysers, or gas detectors. The built-in power supply allows the multichannel controller to power the monitors located up to 100 feet away. The 2 adjustable relays allow you to create desired audible warnings notifying workers.

The 8-channel controller allows you to take channels offline individually for easy calibration or sensor maintenance. While one channel is offline, the other systems will continue to operate normally.

The multichannel controller allows you to set specifications for each gas sensor for quick differentiation. The LCD graphical display shows current data across all connected channels or trend data over a selected time period. You can manage controller display data in percentage, parts-per million (ppm), or parts-per-billion (ppb). An RS-485 Modbus communication interface is available upon request.
