Product Introduction
The CCL-1 Intelligent Residual Gas Content Measuring Instrument is used to test coal mine gas content indicators. This product complies with the standards GB/T23250-2009 "Direct Determination Method of Coal Seam Gas Content in Underground Mines" and AQ 1046-2007 "Determination Method of Coal Seam Gas Content During Geological Exploration." It utilizes programmed intelligent control and sensor principles to automate the gas testing process using the degassing method, achieving programmed operations for degassing, gas collection, water circulation, data acquisition, and other functions. The equipment features an integrated design, high testing efficiency, and minimal human operational error, making it one of the essential products for testing basic parameters in modern mine safety production.
Technical Features

The CCL-1 Intelligent Residual Gas Content Measuring Instrument is used for the precise measurement of residual gas content and desorbable gas volume in coal seams. When used in combination with laboratory equipment, underground coal mine sampling, sealed tanks, and desorption devices, it enables computer-intelligent full-process measurement, control, and monitoring.
