Dga Insulating Oil Gas Content Analyzer Transformer Oil Dissolved Gas Analyzer

Product Description

DGA Insulating Oil Gas Content Analyzer Transformer Oil Dissolved Gas Analyzer
Introduction
1) GC is an effective means to achieve gas chromatography. Gas chromatography with a high-performance high selectivity, high sensitivity, rapid analysis, small sample volume, wide range of applications and so on. Chromatography can be widely used systems and scientific research institutes and universities in areas such as health and epidemic prevention, environmental monitoring, quality supervision, petrochemical, pharmaceutical, commodity inspection, public security, food, electricity, liquor, mines and so on.
2) GDGC-7890-DL Series gas chromatograph is controlled by a microcomputer, a higher cost performance of the gas chromatograph, can be equipped with a thermal conductivity detector (TCD), flame ionization detector (FID). Can be installed packed column and capillary column oven can be heated and temperature-programmed operations.
