Universal Gas Detector with Remote Sensor

Item #: 99031

Product Summary

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
  • 4-20m A 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
  • 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.

Low Annual Operation Cost

The Universal Gas Detector has the lowest annual maintenance costs of any gas monitoring system on the market. PureAire Renewable sensors are easily recharged with electrolyte right in the field at approximately 20% of the cost of disposable sensor cell type systems. Routine maintenance materials are $70 per year and when compared to the high cost of disposable sensors, can save you hundreds of dollars in annual service!

Stand-Alone Monitoring

The Universal Gas Detector is designed to operate totally stand-alone. Just mount it to the wall near the risk site and plug in the wall wart regulated power supply into any 115VAC 60 Hz outlet or 220VAC 50 Hz outlet and you’re up and monitoring. The built-in horn and LED alarm indicators quickly alert personnel to a hazardous condition. It also has individual alarm and fault relays for connecting remote alarms or control and the analog 4-20mA output provides continuous data to remote PLC and SCADA systems.

Continually supervised electronics

The Universal Gas Detector detectors “smart” circuitry is continuously supervised 24-7 and should a system error occur, the detectors analog output and fault relay immediately alerts control room personnel to the problem. A dedicated microcontroller built directly into the sensor allows you to remove from it the transmitter for all routine calibration and maintenance. Calibration data is directly entered into the sensor electronics and then transferred to the transmitter once it’s plugged in.
