Carbon Monoxide Gas Detector

Carbon Monoxide Gas Detector

Item #: 95107


Product Summary

PureAire’s Carbon Monoxide Gas Detector is used for safety in laboratories, parking garages, or facilities requiring safe CO detection. The detector comes with two alarm relays that send a signal to the horn/strobe, building systems, etc. In addition, the Carbon Monoxide Gas Detector includes built-in visual alarms with bright LEDs, a 4-20mA analog output, and 24/7 supervised electronics that continuously check the sensor.

  • CO, IPA, H2, H2S, and Other Toxic Gases
  • Dual Sensor Capability
  • Non-Intrusive One-man Calibration
  • Ex Proof Enclosure Div 1 & 2, Group B, C, & D
  • Local Digital Display with Bargraph & Trending
  • User Adjustable Dual Alarm Relays
  • 4-20 mA Analog Output
  • RS-485 Modbus Optional
  • NRTL CSA Approvals, ATEX Optional

The Carbon Monoxide Gas Detector’s instrument fault supervision circuitry continuously monitors for failed sensor cells and communication line breaks. Sensor cell operation is also continuously supervised 24/7 and, when used in conjunction with distributive control systems or PLCs, provides immediate fault identification for a disconnected sensor cell.

The Carbon Monoxide Gas Detector is housed in a NEMA 7 explosion-proof enclosure and is available for Carbon Monoxide, IPA, H2, H2S, and other toxic gases. It can monitor ppm levels of toxic gases or % LEL levels of combustible gases, making it a perfect monitoring solution for providing worker protection in chemical plants, refineries, and other areas requiring hazardous classifications.

When released into the air, carbon monoxide can cause harm or even be fatal if inhaled or exposed for prolonged periods. The Occupational Safety and Health Administration (OSHA) lists toxic gases and their permissible exposure limits (PELs) to CO before they reach an unsafe level.
