A1220 Insulating Oil Gas Chromatograph Introduction
The A1220 gas chromatograph is designed and manufactured according to the methods specified in GB / T 17623 and DL / T 703 standards, and is suitable for analyzing oil-filled electrical equipment (including transformers, reactors, current transformers, voltage transformers, charging bushings). Etc.) Analysis of hydrogen, carbon monoxide, methane, carbon dioxide, ethylene, ethane, acetylene and other gas contents dissolved in insulating oil. Features
High sensitivity, high accuracy, high resolution, high analysis speed, simple analysis method.
One chromatographic column has good separation effect.
One injection, less injection volume; short time for full analysis.
The data is processed automatically by the chromatography workstation. Technical Parameters
