Product Specification

Air check Ex Combustible Gas Monitor

The Air check Ex is a compact gas monitoring system that's ideal for continuously monitoring toxic and corrosive gases in hazardous areas. The Air check Ex non-intrusive calibration allows sensor calibration in hazardous areas without area declassification. The only tool required is a small magnetic wand, designed to be carried on a technician's key chain. It also allows true one-man calibration, which significantly reduces the labor and downtime commonly associated with gas detector maintenance and service.

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 PLC's, provides immediate fault identification for a disconnected sensor cell.

The Air check Ex is housed in a Nema 4 explosion proof enclosure and is available for hydrogen gas. Capable of monitoring the % LEL hydrogen, the Air check Ex is a perfect monitoring solution for providing worker protection in chemical plants, refineries and other areas requiring hazardous classifications.

Air check Ex Combustible Gas Monitor Features
• Non-Intrusive one-man calibration
• Ex proof enclosure
• Designed for Combustible gases
• Local digital display
• 4-20 mA analog output
• Long Life LEL catalytic sensor
