The PureAire 32-Channel Touch Screen Programmable Controller remotely operates and powers up to 32 fixed gas monitors in spaces where oxygen and other gas levels pose a safety hazard to personnel or operations.
The multi-channel controller connects up to 32 monitors — continuously measuring inert and toxic gases including, but not limited to, oxygen, carbon dioxide, helium, argon, nitrogen, ammonia, chlorine, hydrogen, methane, ethylene, and propane — from a distance of up to 100 feet.
It accepts any 2- or 3-wire gas detector and features 4 user-adjustable common alarm relays that alert personnel in the event of a gas leak or a monitor fault by controlling a horn or strobe. Individual channels can be taken offline for calibration or sensor maintenance, and each channel can be designated in PPM, PPB, or %. The LCD color touch screen displays the readings from all channels simultaneously, with trend graphs viewable over time.
Housed in a NEMA 4X / IP67 water-resistant enclosure with a built-in 24 VDC power supply and RS-485/Modbus RTU output — backed by a 2-year warranty.
