Insulated gas decomposition meter working principle
Sulphur hexafluoride is an inorganic, colourless, odourless, non flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.
