Hydraulic prop column is mine sulfur dioxide GSH50 sensor 0-50ppm, mining sulfur dioxide alarm CSH50 is a portable intrinsically safe sulfur dioxide detector for measuring the mines of sulfur dioxide. Instrument imported electrochemical sensor, responsive, accurate and reliable. Compact size and light weight make it can be very comfortable to wear in the pocket and helmet. As a high-end sensors, even if you put it in your shirt pocket, it can also provide continuous and unobstructed protection. Sensors for combustible gases in coal mine explosion in the environment for the implementation of the concentration of sulfur dioxide continuous automatic monitoring, sampling the unique structure, greatly improving the detection devices in harsh environments to prevent impurities pollution capacity to ensure the accuracy of measurement. The whole machine adopts microcomputer, and an integrated digital circuits, sulfur dioxide with high-precision components, with stable performance, high accuracy, fast response, anti-interference ability, simple structure, easy maintenance, maximum allowable concentration of sulfur dioxide underground 5ppm.
