    Sulphur Hexafluoride. NDIR sensors for measuring SF 6 leaks. 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.

    Carbon dioxide (CO 2) in ambient and standard air samples is detected using a non-dispersive infrared (NDIR) analyzer. The measurement of CO 2 in air is made relative to reference standards whose CO 2 mixing ratio is determined with high precision and accuracy. Because detector response is non-linear in the range of atmospheric levels, ambient samples are bracketed during analysis by a set of reference standards used to calibrate detector response.
