GD-3100E Portable Transformer Oil Analysis Gas Chromatograph Detector Transformer Dga Dissolved Gas Analysis
 

Product description

GD-3100E Portable Transformer Oil DGA Chromatograph adopts the classic three-detector process, a sample can be completed in the insulating oil dissolved in the content of H2, CO, CO2, CH4, C2H4, C2H6, C2H2 and so on 7 kinds of gas components of the whole analysis. The instrument integrates computer, gas source and other components together, and the whole system is compressed into 2 pieces of portable chromatography and portable oscillator, which makes it portable in the true sense.

Compliance with standards


1,GB/T 17623-2017 Determination of dissolved gas components in insulating oil by gas chromatography
2,GB/T 7252-2001 Guidelines for analysis and judgment of dissolved gases in transformer oils
3,DL/T 722-2014 Guidelines for analysis and judgment of dissolved gases in transformer oils

Technical characteristics
