## Description

The RKI FP-300 is a compact paper tape toxic gas monitor that uses colorimetric tape for interference-free detection at low ppb and ppm levels of ammonia, arsine, chlorine, diborane, hydrogen chloride, hydrogen fluoride, hydrogen sulfide, phosphine and silane. It has audible and visual alarms, alarm relays and a 4-20 mA output.
- Highly sensitive: ppb detection for low gas concentrations
- Interference-free: no response to hydrocarbons, alcohols, solvents or CO
- Plug-in tape cassette, easy to replace; tape remainder display and tape-end warning
- Tape saver mode extends tape life where background gas is present
- Audible and visual 2-level alarms, alarm relay contacts and 4-20 mA output
- Panel-mount (24 VDC) or desktop (AC) versions; small and easily transportable
