Description
The OGC-9820Pro Insulation Oil Gas Chromatograph Analyzer is a professional, high-precision laboratory-grade instrument engineered for comprehensive dissolved gas analysis (DGA) of insulating oils used in high-voltage electrical equipment. Adopting advanced dual-detector (FID + TCD) technology with a nickel catalyst converter and fully automatic headspace sampling system, it delivers accurate, repeatable measurement of 9 characteristic dissolved gases generated by transformer insulation degradation under thermal and electrical stress.
With an industry-leading detection limit of 0.01ppm for acetylene (C2H2), 15-minute fast analysis per sample, and built-in multi-algorithm fault diagnosis software, this analyzer enables early detection of internal transformer faults such as partial discharge, overheating, arcing, and insulation breakdown. Fully compliant with IEC 60567, ASTM D3612-C, GB/T 7252, and GB/T 17623 international and domestic standards, it is the definitive solution for power utilities, transformer manufacturers, industrial maintenance teams, third-party testing institutions, and research laboratories worldwide. It is optimized for new oil incoming inspection, in-service oil routine monitoring, post-fault diagnosis, and transformer lifecycle management.
