Product Description 
 MD-98 coal drill cuttings gas desorption instrument (hereinafter referred to as the instrument) is mainly used for coal and gas outburst in underground mine CROSSCUTTING coal, coal roadway and stope prominent risk prediction, testing anti-anti-conflict effects of sudden measures, etc. , and must be determined one of the important indicators of coal and gas outburst coal cuttings gas desorption index Δh2 value. The instrument uses advanced micro-differential pressure sensor, combined with the MCU control technology and air flow control technology, developed a new measuring instrument suitable for China's coal mine safety production needs. Coal and gas outburst prevention and control work to accurately and quickly, saving time, the whole process of automation at the job site directly predict its parameters, all the determination process takes only 5 min.
