GC****0D Gas Chromatograph Transformer Oil Dissolved Gas Analyzer

GC****0D is specially designed for determination of the gas content dissolved in the transformer oil. It consists of a packed column injection system, two packed columns (a porous polymer column and a carbosieve column), a methanator and three detectors (two flame ionization detectors and a thermal conductivity detector).
