YHFJW SF6 decomposition product testerA simple on-site detection method for SF6 decomposition products is provided. During use, connect to a pressurized chamber filled with SF6 gas and allow SF6 gas to flow through an electrochemical sensor at a certain flow rate. The instrument directly measures the content of the main decomposition products of SF6 gas. The sensors used in this instrument are all British Alpha sensors with a long lifespan design, ensuring the accuracy and reproducibility of measurement results.
The YHFJW SF6 gas decomposition product tester is mainly used for fault location, routine detection, partial discharge monitoring, gas purification/filtration monitoring, fault high-voltage contact inspection, SF6 decomposition product detection, and checking the generation of decomposition products inside switches.
