For the requirements of accurate measuring of SF6 gas purity and decomposition in the electric industry, the design of a detector was put forward.The digital infrared SF6 gas sensor and H2 S, SO2 and CO electrochemistry sensors were integrated. The analog signals of electrochemistry sensors were processed and converted into digital signals, which were put into STM32F103 with the digital signal of SF6 sensor to be processed and controlled.Complete software architecture made the detector equipped with the functions of calibration, storage, inquiry, communication and so on.Through temperature compensation and sensor data ma-trix, the accuracy was guaranteed.The results show that the relative error of SF6 purity is less than 0.04%, and the relative error of the decomposition is less than 2.0%.
