The carbon monoxide gas monitor is used for safety in laboratories, or facilities requiring safety detection of CO. The CO gas detector comes with 2 alarm relays with signal to horn/strobe, building systems, etc. There are built-in visual alarms with bright LEDs, a 4-20mA analog output, and 24/7 supervised electronics which continuously checks the sensor.
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.
