Dgc-a gas content direct measuring device

  The dgc-a gas content direct measuring device includes basic indexes such as desorption gas content, residual gas content and original gas content
The mine gas content index is one of the important parameters for the prediction of mine gas emission, the prediction of coal and gas outburst risk areas, the evaluation of pre drainage gas results and the preparation of gas geological map
The performance characteristics of dgc-a gas content direct measurement device are short, and the measurement time after sampling is less than 2 hours; A large number of sampling tests can be carried out; The reliability and accuracy of the determination are high; It can realize the conversion calculation of gas content and gas pressure, the automatic calculation of mathematical model of gas loss, and has the functions of bidirectional output, query and printing of experimental process report and experimental result report; Electronic digital display temperature measurement and pressure sensing system are adopted to improve the timeliness of test; The desorption metering system can customize the automatic acquisition mode of liquid level sensor, reduce the experimental error caused by human factors and improve the intelligence of equipment
