It is calibrated specifically for R22 refrigerant and delivers accurate concentration readings across a 0–1000 ppm measurement range. The sensor outputs a standard 4–20 mA signal for reliable communication with compatible monitoring and alarm systems. Designed for flexible power input, it operates on 22–27 VAC at 48 VA (50\/60 Hz) or 22–38 VDC up to 2 A maximum, making it suitable for commercial HVAC and mechanical room installations.\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-start=\"372\" data-end=\"828\"\u003e\u003cstrong data-end=\"1102\" data-start=\"1085\"\u003eKey Features:\u003c\/strong\u003e\u003cstrong data-end=\"1102\" data-start=\"1085\"\u003e\u003c\/strong\u003e\u003cstrong data-end=\"1102\" data-start=\"1085\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eR22-Specific Detection: Calibrated for accurate monitoring of R22 refrigerant gas.\u003c\/li\u003e\n\u003cli\u003e0–1000 ppm Measurement Range: Enables precise leak detection within typical exposure limits.\u003c\/li\u003e\n\u003cli\u003e4–20 mA Output Signal: Provides standardized analog output for control system integration.\u003c\/li\u003e\n\u003cli\u003e301-EM Compatibility: Designed for use with Honeywell 301-EM gas monitoring controllers.\u003c\/li\u003e\n\u003cli\u003eDual Power Options: Operates on 22–27 VAC (50\/60 Hz) or 22–38 VDC.\u003c\/li\u003e\n\u003cli\u003eInfrared Sensing Technology: Enhances stability and reduces cross-sensitivity.\u003c\/li\u003e\n\u003cli\u003eContinuous Monitoring Capability: Suitable for mechanical rooms and refrigeration spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe S301-IRF-R22 delivers the reliability and precision required for refrigerant leak detection and safety monitoring in commercial HVAC systems.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":51167983108394,"sku":"S301-IRF-R22","price":3499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/301irf-main-image_800x_60efbbbf-d28e-4c3a-9a2d-23b1f45dee12.jpg?v=1771579273","url":"https:\/\/iqelectro.com\/products\/honeywell-s301-irf-r22-refrigerant-gas-sensor-fast-shipping","provider":"IQElectro","version":"1.0","type":"link"}
