Product Description
■ Product Overview
The transformer oil chromatography analyzer is suitable for determining the concentrations of dissolved gas components in insulating oil used in power systems, and a single injection is sufficient to analyze the dissolved gases in the insulating oil. 7 Gas component species H2、 CO 、CO2、CH4、C2H4、C2H6、 C2H2( Hydrogen, carbon monoxide, carbon dioxide, methane, ethylene, ethane, acetylene ) A comprehensive analysis of the content, with a minimum detection limit for acetylene reaching 0.1ppm . [Main Testing] :H2 、 CO 、CO2、CH4、C2H4、C2H6、C2H2 As the primary basis for fault diagnosis , It is recommended to test whenever possible. :02 、N2 As an auxiliary judgment ( That is 9 Type of gas )。
