{"product_id":"rki-sd-1-fixed-gas-detector","title":"RKI SD-1 Fixed Gas Detector","description":"\u003cp\u003eThe RKI SD-1 is a compact, explosion-proof fixed gas detector head available across five sensor platforms — electrochemical (EC) for toxic gases like CO and H2S, catalytic combustible sensors (GH and GP) covering dozens of solvents and flammable gases, galvanic oxygen (OX), and infrared (RI\/DRI) for combustibles resistant to catalytic poisoning. All output 4-20mA, with HART communication available on select sensors.\u003c\/p\u003e\n\u003cp\u003eATEX\/IECEx Ex d IIC T5 rated with IP-65\/67 housing, the SD-1 is built for LNG terminals, petrochemical plants, power stations, utilities, and steel works. RKI's SD-1GH platform alone covers 25+ specific solvent and VOC gases — the configurations listed here are the most commonly ordered across each sensor type; other gas-specific calibrations are available by quote.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"SD-1EC: Carbon Monoxide (0-75 ppm)","offer_id":48206489551038,"sku":"SD-1EC-CO","price":1020.0,"currency_code":"USD","in_stock":true},{"title":"SD-1EC: Hydrogen Sulfide (0-30 ppm)","offer_id":48206489583806,"sku":"SD-1EC-H2S","price":1020.0,"currency_code":"USD","in_stock":true},{"title":"SD-1GH: Methane (0-2,000 ppm)","offer_id":48206489616574,"sku":"SD-1GH-CH4-2K","price":783.75,"currency_code":"USD","in_stock":true},{"title":"SD-1GH: Benzene (0-500 ppm)","offer_id":48206489649342,"sku":"SD-1GH-BNZ-500","price":783.75,"currency_code":"USD","in_stock":true},{"title":"SD-1GH: Ammonia (0-500 ppm)","offer_id":48206489682110,"sku":"SD-1GH-NH3-500","price":783.75,"currency_code":"USD","in_stock":true},{"title":"SD-1GH: Ethanol (0-2,000 ppm)","offer_id":48206489714878,"sku":"SD-1GH-ETH-2K","price":783.75,"currency_code":"USD","in_stock":true},{"title":"SD-1GH: Xylene (0-1,000 ppm)","offer_id":48206489747646,"sku":"SD-1GH-XYL-1K","price":783.75,"currency_code":"USD","in_stock":true},{"title":"SD-1GP: Methane (0-100% LEL)","offer_id":48206489780414,"sku":"SD-1GP-CH4","price":667.5,"currency_code":"USD","in_stock":true},{"title":"SD-1GP: Hydrogen (0-100% LEL)","offer_id":48206489813182,"sku":"SD-1GP-H2","price":667.5,"currency_code":"USD","in_stock":true},{"title":"SD-1GP: LPG (0-100% LEL)","offer_id":48206489845950,"sku":"SD-1GP-LPG","price":667.5,"currency_code":"USD","in_stock":true},{"title":"SD-1OX: Oxygen (0-25% vol)","offer_id":48206489878718,"sku":"SD-1OX","price":941.25,"currency_code":"USD","in_stock":true},{"title":"SD-1RI: Isobutane (0-100% LEL, IR)","offer_id":48206489911486,"sku":"SD-1RI-IC4H10","price":1102.5,"currency_code":"USD","in_stock":true},{"title":"SD-1DRI: Methane (0-100% LEL, IR)","offer_id":48206489944254,"sku":"SD-1DRI-CH4","price":1297.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/SD-1EC.jpg?v=1785125807","url":"https:\/\/envirotechonline.com\/products\/rki-sd-1-fixed-gas-detector","provider":"EnviroTech Services","version":"1.0","type":"link"}
