dual infrared sensing technology for stable and selective detection performance. It is compatible with Honeywell 301EM-20 controllers and SQN8X platforms, communicating via 4–20 mA output and RS-485 Modbus networks. The sensor operates on 22–27 VAC at 48 VA (50\/60 Hz) or 22–38 VDC at 2 A maximum and supports transmitter distances up to 500 feet depending on configuration. Designed for multi-gas refrigerant monitoring, it provides a measurement range of 0–1000 ppm with a 20 ppm deadband and recommended 6-month calibration interval.\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-end=\"828\" data-start=\"372\"\u003e\u003cstrong data-start=\"1085\" data-end=\"1102\"\u003eKey Features:\u003c\/strong\u003e\u003cstrong data-start=\"1085\" data-end=\"1102\"\u003e\u003c\/strong\u003e\u003cstrong data-start=\"1085\" data-end=\"1102\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInfrared Refrigerant Detection: Dual IR sensor technology for stable and selective gas monitoring.\u003c\/li\u003e\n\u003cli\u003e0–1000 ppm Measurement Range: Suitable for low-level leak detection in mechanical spaces.\u003c\/li\u003e\n\u003cli\u003e1 ppm Resolution: Enables precise gas concentration monitoring.\u003c\/li\u003e\n\u003cli\u003e4–20 mA Output: Standard analog signal for integration with control systems.\u003c\/li\u003e\n\u003cli\u003eRS-485 Modbus Communication: Supports networked monitoring applications.\u003c\/li\u003e\n\u003cli\u003eMulti-Gas Compatibility: Detects R11, R12, R123, R125, R134A, and R22 refrigerants.\u003c\/li\u003e\n\u003cli\u003eVisual \u0026amp; Audible Alarms: LED status indicators and 65 dBA internal audible alert.\u003c\/li\u003e\n\u003cli\u003eNEMA 1 Enclosure: Designed for indoor commercial installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe S301-IRF-R123 delivers the reliability and precision required for refrigerant leak detection and environmental safety monitoring in commercial HVAC and industrial facilities.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":51167988482346,"sku":"S301-IRF-R123","price":3369.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l960_d6174181-4db4-4241-80a1-3f640ad5a2c8.webp?v=1771580165","url":"https:\/\/iqelectro.com\/products\/honeywell-s301-irf-r123-refrigerant-gas-sensor-ships-fast","provider":"IQElectro","version":"1.0","type":"link"}
