{"product_id":"rki-gd-70d-sample-draw-smart-transmitter","title":"RKI GD-70D Sample-Draw Smart Transmitter","description":"\u003cp\u003eThe RKI GD-70D is a compact, sample-draw smart transmitter built around a common sensing platform covering 50+ specialty toxic, corrosive, and combustible gases from one wall-mounted housing. An internal 0.5 L\/min auto-adjusting pump draws sample to the sensor, and an optional Pyrolyzer\/PLU-70 conditioning unit extends coverage to compounds like TEOS, TEB, TEOP, and NF3 used in vaporized hydrogen peroxide (VHP) disinfection and semiconductor CVD processes.\u003c\/p\u003e\n\u003cp\u003eStandard output is 4-20mA, with optional Ethernet (10\/100BASE-T) connectivity or Lonworks networking, and dry-contact relays for 1st\/2nd\/trouble alarms. Choose the compact standard housing or a NEMA 4X enclosure, the latter available with an integrated horn\/strobe or Federal Signal strobe for local alarm annunciation; a no-sensor base unit is also available for facilities specifying their own sensor cartridge separately. Power is 24VDC ±10% (~1.5-4W standard, up to 25W with the Pyrolyzer). The configurations listed here cover the most commonly ordered gas types and housings — RKI builds dozens of additional gas-specific and housing configurations by quote.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"CH4 (Methane) 0-100% LEL, Standard","offer_id":48206562951358,"sku":"GD-70DEA-LELCH4","price":1177.5,"currency_code":"USD","in_stock":true},{"title":"H2 (Hydrogen) 0-100% LEL, Standard","offer_id":48206562984126,"sku":"GD-70DEA-LEL-H2","price":1177.5,"currency_code":"USD","in_stock":true},{"title":"CO (Carbon Monoxide) 0-150 ppm, Standard","offer_id":48206563016894,"sku":"GD-70DEA-CO-01","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"O2 (Oxygen) 0-25% Vol, Standard","offer_id":48206563049662,"sku":"GD-70DEA-OXY-EC","price":1335.0,"currency_code":"USD","in_stock":true},{"title":"H2S (Hydrogen Sulfide) 0-30 ppm, NEMA 4X","offer_id":48206563082430,"sku":"GD-70DEA4XH2S30","price":1890.0,"currency_code":"USD","in_stock":true},{"title":"NH3 (Ammonia) 0-75 ppm, Standard","offer_id":48206563115198,"sku":"GD-70DEA-NH3","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"Cl2 (Chlorine) 0-3.00 ppm, Standard","offer_id":48206563147966,"sku":"GD-70DEA-CL2","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"HCN (Hydrogen Cyanide) 0-15 ppm, Standard","offer_id":48206563180734,"sku":"GD-70DEA-HCN","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"PH3 (Phosphine) 0-1.00 ppm, Standard","offer_id":48206563213502,"sku":"GD-70DEA-PH3-DH","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"NO2 (Nitrogen Dioxide) 0-9.0 ppm, Standard","offer_id":48206563246270,"sku":"GD-70DEA-NO2-09","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"O3 (Ozone) 0-0.60 ppm, Standard","offer_id":48206563279038,"sku":"GD-70DEA-O3","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"AsH3 (Arsine) 0-0.20 ppm, Standard","offer_id":48206563311806,"sku":"GD-70DEA-ASH3","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"SiH4 (Silane) 0-15 ppm, Standard","offer_id":48206563344574,"sku":"GD-70DEA-SIH4AH","price":1260.0,"currency_code":"USD","in_stock":true},{"title":"Toxic Gas Monitor, No Sensor (Base Unit)","offer_id":48206563377342,"sku":"GD-70DEA-NS","price":870.0,"currency_code":"USD","in_stock":true},{"title":"TEOS 0-15 ppm, with Pyrolyzer","offer_id":48206563410110,"sku":"GD-70DPEA-TEOS","price":2002.5,"currency_code":"USD","in_stock":true},{"title":"CH4 (Methane) 0-100% LEL, NEMA 4X","offer_id":48206563442878,"sku":"GD-70DEA4X-LCH4","price":1807.5,"currency_code":"USD","in_stock":true},{"title":"O2 (Oxygen) 0-25% Vol, NEMA 4X","offer_id":48206563475646,"sku":"GD-70DEA4XOXYEC","price":1965.0,"currency_code":"USD","in_stock":true},{"title":"H2 (Hydrogen) 0-100% LEL, NEMA 4X with Horn \u0026 Strobe","offer_id":48206563508414,"sku":"GD-70DEA4J-LH2","price":2201.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/gd70d_transmitter.jpg?v=1785127333","url":"https:\/\/envirotechonline.com\/products\/rki-gd-70d-sample-draw-smart-transmitter","provider":"EnviroTech Services","version":"1.0","type":"link"}
