The Model IR400 Point IR Combustible Gas Detector features a three-second T90 response time to the presence of combustible hydrocarbon-based gases, which allows plant operators to respond quickly to gas leaks and avoid potential accidents. With its fast three-second response time, the Model IR400 Infrared Gas Detector provides an added margin of safety in protecting people, equipment and plants from potentially explosive gas leaks. The Model IR400 features rapid fail-to-safe continuous gas/vapor monitoring within the lower explosive limit (LEL).  It reliably alerts plant employees to gas leaks and warns them to shut down processes in affected areas.The low maintenance Model IR400 gas detector monitors hydrocarbon-based gases including methane, propane, ethane, ethylene, butane, hexane, pentane and benzene.  It features a self-diagnostic design to prevent false alarms and process shutdowns.  It monitors conditions such as supply voltage and optical path integrity.  The IR400 also features heated optics to eliminate condensation, and a dirty optics indicator helps discriminate between true alarms and maintenance needs.   The user-friendly Model IR400 uses only 4.8 W of power. It is designed for operational efficiency and system problem-detection capability.  Additionally, the detector requires no routine calibration, a feature that reduces demand for field technician maintenance time. The IR400 operates by measuring the absorption of infrared radiation passing through a volume of gas using a dual beam, single detector method.  The IR detector measures the intensity of two specific wavelengths, one at an absorption wavelength and another outside of the absorption wavelength.  The gas concentration is determined by comparing these two intensities.
