PointWatch™ (PIR9400) IR Gas Detector
The PIR9400 is well 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’s ability to detect hazards.
- Requires no routine calibration to ensure proper operation.
- Continuous self-test automatically indicates a fault or fouled optics condition.
- Unique multi-layered filtering system protects optics from dirt and water ingress.
- Provides a 4-20 mA output signal, corresponding to the detected gas concentration
- Compact, lightweight, explosion-proof housing is designed for duty in harsh environments.
- Standard 0 to 100% LFL detection range.
- Internal heating system minimizes condensation, allowing reliable operation through temperature extremes.
- There are no known poisons, e.g. silicones or hydrides, that compromise the integrity of the measurement.
- Performs well in the presence of high concentrations or constant background levels of hydrocarbons, and in oxygen depleted atmospheres.
- Compliance to ANSI/ISA 12.13.01-2000 performance standard.
