Description
The PointWatchTM Infrared Gas Detector Model PIR9400 is a diffusion-based point-type infrared gas detector. The PointWatch Detector is approved to provide continuous monitoring of methane gas concentration in the range of 0–100% LFL. The detector provides a 4-20 mA output signal, corresponding to the detected gas concentration. It has Division and Zone explosion-proof ratings and is suitable for use in indoor and outdoor applications. The PointWatch Detector Model PIR9400 is ideally suited for use in harsh environments and where the cost of required maintenance for conventional catalytic detectors is prohibitive. It will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology.
