■ Product overview

The SF6 gas decomposition product tester provides a simple on-site detection method for SF6 decomposition products. During use, it is connected to a pressurized gas chamber filled with SF6 gas equipment, and SF6 gas flows through the electrochemical sensor at a certain flow rate, and the instrument directly measures the content of the main decomposition products of SF6 gas.

The sensors all adopt the British Alpha sensor, and the long-life design ensures the accuracy and reproducibility of the measurement results.

Main applications: fault location, routine detection, partial discharge monitoring, gas purification or filtration monitoring, fault high-voltage contact inspection, SF6 decomposition product detection, and inspection of decomposition products in the switch.
