Product Summary

The carbon monoxide gas monitor is used for safety in laboratories, or facilities requiring the safety detection of CO. The CO gas detector comes with 2 alarm relays with a signal to the horn/strobe, building systems, etc. There are 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

The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication line breaks. Plus sensor cell operation is 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 AirCheck Ex is housed in a NEMA 7 explosion-proof enclosure and is available for Carbon Monoxide, IPA, H2, H2S, and other toxic gases. Capable of monitoring ppm levels of toxic gas or % LEL levels of combustible gases, the AirCheck Ex is a perfect monitoring solution for providing worker protection in chemical plants, refineries, and other areas requiring hazardous classifications.
