Riken Keiki FI-8000 Optical gas detector
The Riken Keiki FI-8000 Gas Detector thanks to its easy-to-read LCD display, outdoor capabilities, and others, is one of the most sought after gas detectors out there.
This highly accurate Optical Gas Indicator is customizable for up to 8 gases and ranges, and uses optical interferometry to acuratley measure a gas concentration in a known base gas, such as air. Numorous gases are available to choose from, and if not listed on our current gas list, please ask, it is probably possible to include.
Because the principle operation is the comparison of the optical refractive index of a gas, there are no moving parts or problems with sensor drift. This gives a stable calibration, allowing for long periods between calibration, thus saving on maintenance cost.
The FI-8000 is the latest model from Riken in a long line of optical interferometers dating back to the 1930’s when Riken’s founder first developed the technology for Methane detection to help prevent explosion accidents on oil tankers and in coal mines.
In the 1970’s Weatherall developed with Riken the instrument for anaesthetic gases. In conjunction with Dr John F Nunn’s research, published in the British Journal of Anaesthesia, helped validate the principle of interference refractometry as a technique suitable for measuring anaesthetic gases such as Halothane, Isoflurane, Sevoflurane, Desflurane and Enflurane.
