The integrated gas content tester main unit uses a touch screen as the human-machine interface; it achieves the complete integration of processes such as coal sample sealing and crushing, natural gas desorption, crushing desorption, lost gas volume, and residual gas volume measurement, all completed underground in one unit; the entire gas content measurement process eliminates the need for traditional drainage methods to measure desorbed gas volume and avoids opening the canister to transfer coal samples;
It automates the measurement of coal seam gas content, generates measurement reports on-site underground in real-time, and automatically stores and displays data;
Through a mobile data processing system software (APP), it wirelessly connects with the main unit to measure gas desorption volume, automatically collect and store desorbed gas volume and desorption time data, automatically calculate lost gas volume based on built-in mathematical models, and generate measurement reports, enabling mutual data transmission between the mobile APP and the main unit.
The battery pack features one intrinsically safe power output and includes overcurrent protection functionality.
