Latching or self-resetting alarms drive yellow caution and red warning lamps, a buzzer, relay contacts, and a 4-20mA output.\u003c\/p\u003e\n\u003cp\u003eAvailable in gas-specific tape versions — ammonia, arsine, chlorine, diborane, hydrogen chloride, hydrogen fluoride, hydrogen sulfide, phosphine, silane, boron trifluoride, ClF3, hydrogen bromide, and a specialty C4F6\/C5F8 version — the FP-300 is offered in panel-mount (24VDC, ~14.3 lb) or desktop (100-220VAC, ~12.1 lb) configurations for semiconductor fab and scrubber exhaust monitoring.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"Base Unit","offer_id":48206358741182,"sku":"FP-300","price":4173.75,"currency_code":"USD","in_stock":true},{"title":"H2S (0-100 ppb)","offer_id":48206358773950,"sku":"FP-300-H2S","price":4173.75,"currency_code":"USD","in_stock":true},{"title":"NH3 (0-4.00 ppm)","offer_id":48206358806718,"sku":"FP-300-NH3","price":4173.75,"currency_code":"USD","in_stock":true},{"title":"Arsine (0-150 ppb)","offer_id":48206358839486,"sku":"FP-300A-ASH3","price":4200.0,"currency_code":"USD","in_stock":true},{"title":"Boron Trifluoride (0-3 ppm)","offer_id":48206358872254,"sku":"FP-300A-BF3","price":4743.75,"currency_code":"USD","in_stock":true},{"title":"ClF3 (0-500 ppb)","offer_id":48206358905022,"sku":"FP-300A-CLF3","price":4743.75,"currency_code":"USD","in_stock":true},{"title":"Hydrogen Bromide (0-2 ppm)","offer_id":48206358937790,"sku":"FP-300A-HBR","price":4743.75,"currency_code":"USD","in_stock":true},{"title":"Phosphine (0-500\/900 ppb)","offer_id":48206358970558,"sku":"FP-300A-PH3","price":4743.75,"currency_code":"USD","in_stock":true},{"title":"C4F6\/C5F8 (0-5.00 ppm)","offer_id":48206359003326,"sku":"FP-300AGZS","price":7286.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/fp-300-papertape-gas-monitor.jpg?v=1785122879","url":"https:\/\/envirotechonline.com\/products\/rki-fp-300-paper-tape-gas-monitor","provider":"EnviroTech Services","version":"1.0","type":"link"}
