The fully automatic gas adsorption constant measuring instrument (hereinafter referred to as the instrument) is mainly used to determine the adsorption constants (a and b values) of coal to gas during the measurement of coal mine gas content. Based on the actual gas pressure measured underground, the gas content per ton of coal seam can be calculated.
