This sensor operates using electrochemical technology for precise measurement of low-level nitrogen dioxide concentrations in ambient air. Designed to communicate with an E3Point base unit through a shielded cable, it provides 4–20 mA analog output for real-time monitoring and alarm activation. Its rugged, corrosion-resistant enclosure and wide temperature range make it suitable for harsh environments such as parking facilities, mechanical rooms, and industrial ventilation systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRemote Sensor Configuration: Designed for external installation away from the E3Point base unit for flexible system deployment.\u003c\/li\u003e\n\u003cli\u003eHigh Accuracy Detection: Electrochemical sensing technology delivers precise NO₂ readings for critical air quality applications.\u003c\/li\u003e\n\u003cli\u003eRugged Construction: Corrosion-resistant enclosure protects against dust, moisture, and environmental stress.\u003c\/li\u003e\n\u003cli\u003eWide Operating Range: Performs reliably in temperatures from -40°F to +122°F (-40°C to +50°C).\u003c\/li\u003e\n\u003cli\u003eAnalog Communication Output: Provides 4–20 mA signal for integration with E3Point systems and building safety controls.\u003c\/li\u003e\n\u003cli\u003eQuick Response Time: Detects nitrogen dioxide changes rapidly for timely warning and ventilation activation.\u003c\/li\u003e\n\u003cli\u003eEasy Maintenance: Field-replaceable sensing element simplifies service and calibration.\u003c\/li\u003e\n\u003cli\u003eSafety Note: Requires power to be disconnected prior to installation for safe setup and operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe E3SRMNO2 delivers the reliability and precision required for effective nitrogen dioxide monitoring and ventilation control in commercial and industrial gas detection applications.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105139302656,"sku":"E3SRMNO2","price":962.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/21IJS6hgC9L.jpg?v=1785541115","url":"https:\/\/alotechparts.com\/products\/e3srmno2-honeywell-e3point-remote-nitrogen-dioxide-no2-sensor","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
