Riken Keiki FPM-80 Multi-point Gas Detector

A Multi-point Tape-type Continuous Monitoring Gas Detection System. The FPM-80 is highly reliable for detecting gases in low concentration and possesses excellent long-term stability as it automatically resets to the zero level after each gas detection. The following are the main functions and special features of the FPM-80:

• A two-tiered alarm system (the first alarm and the second alarm) is employed.
• The gas detection tapes are a cassette tape type which makes replacement of tapes straightforward.
• Replacing the gas detection cassette tape every 6 months maintains the prescribed performance.
• When a detection target gas drawn by a pump contacts the gas detection tape, the tape undergoes a color reaction according to the gas concentration. The monitor detects the ratio of color change (change in the light reflection rate) before and after the gas contact, and converts it into the gas concentration.
• Thanks to the gas detection principles underlying the FPM-80, it is almost completely unaffected by alcohol or interference gases such as hydrogen.
