  • Designed to control and power 8 monitors
  • Connects any 2-wire or 3-wire gas sensors
  • Digital and graphic LCD gas concentration
  • RS-485/Modbus RTU output
  • Built-in power supply
  • NEMA 4X IP66 Water-Resistant Enclosure

The PureAire Multi-channel Controller connects 2-wire or 3-wire to oxygen monitors, analyzers, or gas detectors. The built-in power supply allows the multi-channel 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 multi-channel 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.
