IR400 Point IR Gas Detector
The IR400 Infrared (IR) Point Detector is a hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication. It features an industry-leading response time of ≤ 3 seconds, even with a splash guard installed. All electronics are contained within an explosion-proof housing so that the IR400's detector information can be processed locally. Configurations with analog output, Modbus and HART are also available.
IR5500 Open Path Infrared Gas Detector
The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LEL-m and ppm-m ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas concentrations at the ppm levels. This feature allows it to alarm faster than an LEL-only detector. Digital display and adjustable mounting arms ensure easy alignment. Factory calibrated for low-maintenance operation.
IR700 Point IR Carbon Dioxide Gas Detector
The IR700 Infrared (IR) Point Detector is a microprocessor-based carbon dioxide gas detector that continuously monitors for CO2 in ppm levels. All electronics are contained within an explosion-proof housing so that the IR700's detector information can be processed locally. The IR700 operates with a 4-20 mA signal, which is proportional to 0 to 100% full scale. Configurations with analog output, Modbus and HART are available. Modbus and HART data can be used for predictive maintenance.
