General Monitors’ Model IR700 Infrared Carbon Dioxide Point Detector offers reliable gas detection performance with low maintenance. It requires no routine calibration and provides control room status and control capability for monitoring at the PPM level. The detector features a precision IR-point-sensing element that protects against the hazards of carbon dioxide gas leaks. It features a fail-to-safe design for dependable gas detection performance, heated optics to eliminate condensation, and a dirty-optics indicator to inform the user the device must be cleaned before the lenses are entirely blocked, thereby reducing downtime. The detector features microprocessor-based technology to continuously monitor CO2 at a range of 0-5000 PPM. It features multiple communication outputs, a 4-20 mA signal proportional to 0-100 percent full scale, Modbus, and HART. The detector is also available with relays for warning, alarm and faults. The detector features accuracy of +/-5 percent of full scale at concentrations less than or equal to 2,500 PPM and +/-10 percent of full scale at higher concentrations. It offers a response time of T50 ≤ 4s, T90 ≤ 8s. It operates at a temperature range of -40 F to 122 F (-40 C to 50 C) and humidity range of 10-95 percent RH, non-condensing. The detector is available in either aluminum or stainless steel housing and is designed for use in Class I, Div. 1 and 2, Groups B, C and D and Zone 1 areas for North America and Zones 1 and 21 internationally. Ingress protection is rated IP66/Type 4X. The detector has CSA, ATEX, and IECEx approvals, CE Marking, and is HART-registered. –
