Features
Theanalyser thermal conductivity gas meter is a analyser gas meter that quantitatively measures gas concentration using the temperature of a platinum wire heated by the cause-and-effect method. Theanalyser continuously measures the concentration of gases such as Helium, Argon, Hydrogen, Methane, Carbon Dioxide with high stability.
