Sales
RKI’s paper tape monitors utilize highly sensitive colorimetric tapes to achieve interference free detection at low PPB and PPM levels of a wide variety of gases. The FP-301 is equipped with an easily replaceable tape that is highly specific to Arsine AsH3 and Hydrogen Selenide H2Se. This model is equipped with a digital display showing the type of gas and concentration in ppb. The FP-301 will also display remaining tape life as well as an end of tape alarm.
The FP-301 has audible and visual alarms, as well as alarm relay contacts and 4-20mA output. A unique “tape saver mode” extends tape life in applications where high background gas levels may be present.
The FP-301 meets and exceeds OSHA and NIOSH compliance requirements, and does not respond to interfering gases (hydrocarbons, alcohols, solvents, CO, etc.) that may be present in industrial/manufacturing environments. FP 301
