  • Insulation gas leakage detector

    Description. Insulation gas leakage detector SF6 LaserGasTest is based on laser photo-acoustic spectroscopy. This method is well known and widely used for goals of detection of various chemicals when efficiency matters. For example, SF6 LaserGasTest can detect the presence of about 10 ppb of sulfur hexafluoride, which is equivalent to the detection of a sulfur hexafluoride molecules of the 100

  • What is a Gas Sensor? Construction, Types Working of Gas

    Gas Sensor Working. The ability of a Gas sensor to detect gases depends on the chemiresister to conduct current. The most commonly used chemiresistor is Tin Dioxide (SnO2) which is an n-type semiconductor that has free electrons (also called as donor). Normally the atmosphere will contain more oxygen than combustible gases.
