RKI’s paper tape monitors utilize highly sensitive colorimetric tapes to achieve interference free gas detection. The FP-330 is equipped with an easily replaceable tape that is highly specific to Formaldehyde. This model is equipped with a digital display showing the type of gas and concentration in PPM. The FP-330 will also display remaining tape life as well as an end of tape alarm.
Easily Transportable
Accurate at WHO Formaldehyde levels
Free of interference from other gases unlike Electro-chemical solutions
Easy to use and maintain
Continuous operation without interuption
Easy connection to external accessories such as remote sounder beacons , data loggers and diallers and BMS
The FP-330 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-330 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 330
