{"product_id":"rki-gx-3r-gas-detector","title":"RKI GX-3R Gas Detector","description":"\u003cp\u003eThe RKI GX-3R is the world's smallest 4-gas monitor, small enough to clip within OSHA's defined breathing zone while still covering LEL, O2, CO, and H2S. Dual-filament catalytic combustible sensing pairs with a 3-5 year electrochemical O2 sensor, and an H2-compensated CO option and combo H2S\/CO micro-sensor are available for facilities that need to filter out cross-interference.\u003c\/p\u003e\n\u003cdiv style=\"border: 1px solid lightgray; text-align: center; width: 100%; padding: 12px;\"\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/pdf\/air_quality\/rki_gx-3r_multi-gas_monitors.pdf\" style=\"font-size: 15px;\" target=\"_blank\"\u003eSPECS\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid lightgray; text-align: center; width: 100%; padding: 12px;\"\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/RKI_Manuals\/GX-3R_Manual.pdf\" style=\"font-size: 15px;\" target=\"_blank\"\u003eMANUAL\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eSampling is diffusion-based by default, with an optional hand aspirator or clip-on motorized pump for confined-space work. A rechargeable lithium-ion battery delivers roughly 25 hours of runtime on a 3-hour charge, and the IP-66\/68-rated housing is rated for a 23-foot drop and carries ATEX, CSA, IECEx, and MED certification. A flashing non-compliance indicator reminds users every 30 seconds if a bump test or calibration is overdue.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"LEL\/O2\/H2S\/CO (4-gas)","offer_id":48206195392702,"sku":"72158012","price":448.0,"currency_code":"USD","in_stock":true},{"title":"LEL\/O2\/H2S (3-gas)","offer_id":48206195425470,"sku":"72158084","price":448.0,"currency_code":"USD","in_stock":true},{"title":"LEL\/O2\/CO (3-gas)","offer_id":48206195458238,"sku":"72-RC-C","price":448.0,"currency_code":"USD","in_stock":true},{"title":"LEL\/O2\/CO (H2-Compensated)","offer_id":48206195491006,"sku":"72-RD-C","price":479.5,"currency_code":"USD","in_stock":true},{"title":"LEL\/H2S\/CO","offer_id":48206195523774,"sku":"72-RE-C","price":437.5,"currency_code":"USD","in_stock":true},{"title":"O2\/H2S\/CO","offer_id":48206195556542,"sku":"72-RF-C","price":437.5,"currency_code":"USD","in_stock":true},{"title":"LEL\/O2 (2-gas)","offer_id":48206195589310,"sku":"72-RG-C","price":416.5,"currency_code":"USD","in_stock":true},{"title":"LEL\/H2S (2-gas)","offer_id":48206195622078,"sku":"72-RH-C","price":416.5,"currency_code":"USD","in_stock":true},{"title":"LEL\/CO (2-gas)","offer_id":48206195654846,"sku":"72-RI-C","price":416.5,"currency_code":"USD","in_stock":true},{"title":"LEL\/CO (H2-Compensated)","offer_id":48206195687614,"sku":"72-RJ-C","price":448.0,"currency_code":"USD","in_stock":true},{"title":"CO\/H2S (2-gas)","offer_id":48206195720382,"sku":"72-RL-C","price":448.0,"currency_code":"USD","in_stock":true},{"title":"LEL Only","offer_id":48206195753150,"sku":"72-RM-C","price":406.0,"currency_code":"USD","in_stock":true},{"title":"O2 Only","offer_id":48206195785918,"sku":"72158005","price":385.0,"currency_code":"USD","in_stock":true},{"title":"CO Only","offer_id":48206195818686,"sku":"72-RP-C","price":385.0,"currency_code":"USD","in_stock":true},{"title":"CO Only (H2-Compensated)","offer_id":48206195851454,"sku":"72-RQ-C","price":416.5,"currency_code":"USD","in_stock":true},{"title":"O2\/CO (2-gas)","offer_id":48206195884222,"sku":"72-RR-C","price":416.5,"currency_code":"USD","in_stock":true},{"title":"O2\/H2S (2-gas)","offer_id":48206195916990,"sku":"72-RS-C","price":416.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/gx3r-inhand.jpg?v=1785119237","url":"https:\/\/envirotechonline.com\/products\/rki-gx-3r-gas-detector","provider":"EnviroTech Services","version":"1.0","type":"link"}
