{"product_id":"rki-fp-301-high-sensitivity-paper-tape-gas-monitor","title":"RKI FP-301 High-Sensitivity Paper Tape Gas Monitor","description":"\u003cp\u003eThe RKI FP-301 is a high-sensitivity version of the FP-300 paper-tape monitor, using a dedicated chemcassette tape tuned specifically for arsine and hydrogen selenide rather than a general-purpose formulation — giving roughly 10x finer resolution than the standard FP-300 arsine tape. A digital LCD reports concentration in ppb or ppm, and an internal sample pump feeds air continuously across the tape for real-time monitoring.\u003c\/p\u003e\n\u003cp\u003eLatched common relay contacts cover warning, alarm, and trouble conditions alongside a 4-20mA output, and the FP-301 is available in panel-mount (24VDC, ~14.3 lb) or desktop (100-220VAC, ~12.1 lb) configurations — built for uncaptured scrubber exhaust and semiconductor fab environmental monitoring where trace-level arsine or H2Se detection matters.\u003c\/p\u003e","brand":"RKI Instruments","offers":[{"title":"High Sensitivity (Arsine 0-15 ppb \/ H2Se 0-200 ppb)","offer_id":48206361559230,"sku":"FP-301","price":4200.0,"currency_code":"USD","in_stock":true},{"title":"Arsine (0-15 ppb)","offer_id":48206361591998,"sku":"FP-301-ASH3","price":4743.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/FP-301_medium_ee125d4b-221e-4052-bc8c-af738ea0c0bd.jpg?v=1785122923","url":"https:\/\/envirotechonline.com\/products\/rki-fp-301-high-sensitivity-paper-tape-gas-monitor","provider":"EnviroTech Services","version":"1.0","type":"link"}
