The WY-98A Adsorption Constant a and b Value Measuring Instrument is primarily used to determine the adsorption constants of coal to gas (a and b values) during the measurement of coal mine gas content. Based on the actual gas pressure measured underground, it can then calculate the gas content per ton of coal seam. The adsorption constant measuring instrument adopts imported sensor technology, computer monitoring, and fully automated computer control of gas charging valves and operating procedures. The measurement process and results comply with China's coal industry standard MT/T752-1997 "Method for Determination of Coal Gas Adsorption Capacity." It is an intelligent measuring instrument capable of automatically storing and printing measurement results and adsorption isotherms.
