The Riken Keiki FI-900 Optical interferometric gas analyser is equipped with a high-reliability optical interferometric sensor. Measurement principle: The gas concentration is detected from the amount of movement of interference fringes that occur due to the difference in the refractive indexes of the sample gas and reference gas. The FI-900 gas analyzer has enhanced self-diagnostic functions to constantly monitor 10 self-diagnostic parameters while diagnosing operating conditions of the device or its usage environment. The Riken Keiki FI-900 is compatible with Modbus communications to constantly monitor not only gas concentrations but also the state of the measurement device. Log data is also recorded on the measurement device and can be checked to identify causes quickly on-site if faults occur with the device. Explosion-proof ATEX/IECEx/Japan Ex.
