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.

The Riken Keiki RX-515, RX-516, RX-517 marine portable combination gas detectors are specially designed and developed for marine applications. When loading tanks are flushed with inert gases, the O2 content drops proportionally to some inert gases used. Catalytic EX sensors need a minimum content of oxygen in the sample gas to be able to measure combustible gases correctly. As this minimum content is not available, instruments with catalytic sensors are not suitable for conducting EX measurements in inert atmospheres. A solution to this problem is to use infrared technology sensors (NDIR). Infrared sensors measure concentrations of combustible gases reliably, even if O2 is not present. With the Riken Keiki RX-515, RX-516 or RX-517 and, its NDIR sensor you are well suited for this kind of application.
