Supply of cheap WTC3 instrument parameters outburst

WTC3 WTC3 instrument parameters outburst outburst parameter instrument Product Name: WTC3 outburst parameter analyzer Brand: KYCJ Model: WTC3 Description: WTC3 outburst parameter analyzer (hereinafter referred to as the tester) the simultaneous and continuous detection of coal seam drilling methane, carbon dioxide concentrations of both gases and pressure. By detecting coal seam gas pressure within the borehole reaches determine whether gas outburst hazard. Also at the same time it is able to detect the concentration of methane and carbon dioxide gas drilling within 1. Overview WTC3 outburst parameter analyzer (hereinafter referred to as the tester) the simultaneous and continuous detection of coalbed methane drilling inside the carbon dioxide concentration and pressure of both gases. Analyzer 8-bit microcontroller as the control unit, using high-precision sensing element, high sensitivity, fast response, the screen with 128 * 64 LCD wide temperature range, showing a clear and reliable. By detecting coal seam gas pressure within the borehole reaches determine whether gas outburst hazard. Also at the same time it is able to detect the concentration of methane and carbon dioxide gas drilling within this only as an auxiliary judge does not have the gas concentration limit alarm function.
