Introduction to GC-7890B Portable Gas Chromatography Instrument

GC-7890B portable gas chromatograph is suitable for measuring the dissolved gas components in transformer oil in the field and laboratory due to potential overheating, discharge and other faults in the insulation oil;

A complete analysis of the content of seven gas components dissolved in insulating oil, including H2, CO, CO2, CH4, C2H4, C2H6, and C2H2, can be completed within 8 minutes with one injection,

And through the dedicated workstation configured, the potential faults of the transformer are analyzed and judged, and the analysis data is completely consistent with traditional laboratory chromatography data.
