WTC3 Gas outburst parameter measuring instrumentDetailed product description：

The WTC3 gas outburst parameter measuring instrument (hereinafter referred to as the measuring instrument) can simultaneously and continuously detect the concentration and pressure of methane and carbon dioxide gases in coal seam boreholes. The measuring instrument uses an 8-bit microcontroller as the control unit and high-precision detection components, with high sensitivity and fast response speed. The screen adopts a wide temperature range 128 * 64 LCD, with clear and reliable display. By detecting the gas pressure inside the coal seam borehole, it is possible to determine whether there is a risk of gas outburst. In addition, it can also detect the concentrations of methane and carbon dioxide gases inside the borehole, which is only used as an auxiliary judgment and does not have the function of gas concentration exceeding the limit alarm.
