YDC6 Portable Gas Drainage Comprehensive Parameter Measuring Instrument Product Introduction
The Gas Drainage Comprehensive Parameter Measuring Instrument is a portable device specifically designed for underground coal mines to simultaneously measure multiple parameters such as methane concentration, carbon monoxide concentration, pressure, temperature, and flow rate in boreholes or main pipelines. The instrument features sampling filtration, automatic drainage, parameter measurement, and data storage functions. It can transmit measurement data wirelessly to a computer for data management, analysis, and report generation.
YDC6 Portable Gas Drainage Comprehensive Parameter Measuring Instrument Performance Features
① Integrated design, simple appearance, lightweight, and easy to carry;
