HZGC-1212A Transformer Oil Dga Dissolve Gas Analyzer
HZGC-1212A Transformer Oil Dga Dissolve Gas Analyzer
The HZGC-1212A transformer oil DGA dissolved gas analyzer adopts a three-detector process as recommended by industry standards. A single sample enables complete analysis of all dissolved gas components in insulating oil, including hydrogen (H₂), oxygen (O₂), methane (CH₄), ethylene (C₂H₄), ethane (C₂H₆), acetylene (C₂H₂), carbon monoxide (CO), and carbon dioxide (CO₂).
