Universal Gas Detector with Remote Sensor

The PureAire Universal Gas Detector is ideal for facilities requiring continuous monitoring of toxic and corrosive gases. The transmitter is designed to be connected to a dedicated, renewable gas sensor which is programmed to a specific type of gas in parts-per-million (ppm). This gas detector is well suited for environments such as laboratories, hospitals, food refrigeration, pharmaceutical manufacturers, and, for any industry applications where toxic, corrosive gases including, but not limited to, ammonia, HF, hydrogen, HCL, bromine, chlorine, sulfur dioxide are used. PureAire’s renewable, long-life sensors will last up to 8 years in a normal environment and can easily be recharged with electrolyte on the user’s own site.

  • Transmitter connects to any PureAire toxic or corrosive gas sensor
  • Plug & Play sensor sets the transmitter gas & measurement range
  • Dual-level user-adjustable alarm relays
  • 4-20mA analog output
  • Built-in horn & visual alarm LEDs
  • Electronics continuously check sensor & systems status
  • Low-cost, long-life renewable sensor
  • Quick, easy sensor calibration
  • Connects to PLC or SCADA controller
  • UL, CUL, and CE Approvals
  • 24V DC Power supply included

The PureAire Universal Gas Detector is a compact gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposures in the workplace. It consists of a generic transmitter/controller connected to a dedicated, renewable gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Universal Gas Detector can also be connected to any programmable logic controller or SCADA system.

The heart of the system is a smart renewable sensor cell that’s programmed with the specific gas and measurement range information. Simply plug the sensor into any Universal Gas Detector transmitter and it’s ready to go. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas calibrated in the maintenance shop away from the transmitter.
