Pointwatch™ (PIR9400) IR Gas Detector
The PointWatch PIR9400 Infrared detector offers the lowest cost of ownership for detection of hydrocarbon combustible gases and vapors. It is virtually maintenance free and will detect gas concentrations within the 0 to 100% LFL range with a corresponding 4-20 mA output signal. Benefits include continuous self-testing, immunity to poisons such as silicone and hydrides, and the ability to perform under harsh conditions.

The PointWatch® detector is a diffusion-based point-type infrared gas detector approved to provide continuous monitoring of methane gas concentrations in the range of 0 to 100% LFL.

The detector provides a 4-20 mA output signal, corresponding to the detected gas concentration.

The detector has Division and Zone explosion-proof ratings and is suitable for use in indoor and outdoor applications.

PointWatch is ideally suited for use in harsh environments and where the cost of required maintenance for conventional catalytic detectors is prohibitive.

The PointWatch IR detector 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.

The PointWatch detector is globally certified for use in Class 1, Divisions 1 and 2, and Zones 1 and 2 hazardous areas.

It is also approved as a stand alone gas detector, and complies with global approvals when connected to a stand-alone approved controller for life safety.

The approved Det-Tronics controllers are the FlexVu® UD10, Infiniti® U9500, R8471, and Eagle Quantum Premier® (EQP).
