{"product_id":"rki-m2a-xl-fixed-gas-detector","title":"RKI M2A-XL Fixed Gas Detector","description":"\u003cp\u003eThe RKI M2A-XL is an explosion-proof fixed gas transmitter in a cast-aluminum NEMA 4X housing, certified Class I Division 1 Groups B, C, D for flammables, CO, H2S, O2, and CO2, with Class I Division 2 coverage for toxic gases. An OLED display shows live readings locally, while three 5A Form C relays and both 4-20mA and Modbus RTU (RS-485) outputs integrate directly into a control system.\u003c\/p\u003e\n\u003cp\u003eRKI builds the M2A-XL around catalytic, galvanic, electrochemical, and IR sensor technology to cover LEL, O2, H2S, CO, CH4, HCN, arsine, and a wide range of other toxic gases — the configurations listed here cover the most common single-gas sensor options; other gas types and remote-detector\/horn-strobe accessory kits are available by quote.\u003c\/p\u003e\n\u003cdiv style=\"display:flex;gap:10px;margin:15px 0;\"\u003e\n\u003ca href=\"https:\/\/www.geotechenv.com\/pdf\/air_quality\/RKI_M2A-XL.pdf\" target=\"_blank\" style=\"border:1px solid lightgray;border-radius:5px;padding:8px 16px;text-decoration:none;color:#333;font-weight:bold;\"\u003eSPECS\u003c\/a\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/RKI_Manuals\/M2A-XL%20Manual.pdf\" target=\"_blank\" style=\"border:1px solid lightgray;border-radius:5px;padding:8px 16px;text-decoration:none;color:#333;font-weight:bold;\"\u003eMANUAL\u003c\/a\u003e\n\u003c\/div\u003e","brand":"RKI Instruments","offers":[{"title":"LEL 0-100% (Catalytic)","offer_id":48206486470846,"sku":"65-2640XL","price":1042.5,"currency_code":"USD","in_stock":true},{"title":"Hydrogen (H2) Specific LEL","offer_id":48206486503614,"sku":"65-2641XL","price":1158.75,"currency_code":"USD","in_stock":true},{"title":"Hydrogen Cyanide (HCN) 0-15 ppm","offer_id":48206486536382,"sku":"65-2642XL","price":1312.5,"currency_code":"USD","in_stock":true},{"title":"Oxygen (O2) 0-25%","offer_id":48206486569150,"sku":"65-2643XL-05","price":1080.0,"currency_code":"USD","in_stock":true},{"title":"Oxygen (O2) 0-25% Partial Pressure","offer_id":48206486601918,"sku":"65-2644XL","price":993.75,"currency_code":"USD","in_stock":true},{"title":"Hydrogen Sulfide (H2S) 0-100 ppm","offer_id":48206486634686,"sku":"65-2645XL-05","price":1158.75,"currency_code":"USD","in_stock":true},{"title":"Carbon Monoxide (CO) 0-300 ppm","offer_id":48206486667454,"sku":"65-2646XL-05","price":1158.75,"currency_code":"USD","in_stock":true},{"title":"Methane (CH4) 0-9,000 ppm","offer_id":48206486700222,"sku":"65-2647XL","price":1102.5,"currency_code":"USD","in_stock":true},{"title":"Arsine (AsH3) 0-1.5 ppm","offer_id":48206486732990,"sku":"65-2648XL-ASH3","price":1196.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/M2A-XL_web.jpg?v=1785125737","url":"https:\/\/envirotechonline.com\/products\/rki-m2a-xl-fixed-gas-detector","provider":"EnviroTech Services","version":"1.0","type":"link"}
