Description
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.
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.

When HCHO exists in the background continuously over 0.03 ppm, the tape on FP-330 advances after every measurement, so the tape is consumed very quickly. In this case, to extend operating time, the Tape Saver mode is provided on the FP-330.
Tape Saver mode is available for all three ranges;
0H: Normal operation.
1H: One measurement during one hour. Tape lasts 15 days with constant background level.
2H: One measurement during two hours. Tape lasts 30 days with constant background level.
