Intelligent Residual Gas Content Measuring InstrumentCCL-1

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 "Method for Determining Coal Seam Gas Content During Geological Exploration." Utilizing principles of intelligent program control and sensors, it automates the gas testing process based on the degassing method, achieving programmed operations for functions such as degassing, gas collection, water circulation, and data acquisition. The equipment features an integrated design, high testing efficiency, and minimal human operational error, making it one of the essential products for testing fundamental parameters in modern mine safety production.

Technical Features

Used for precise measurement of residual gas content and desorbable gas volume in coal seams. When combined with laboratory equipment, underground sampling, sealed tanks, and desorption devices in coal mines, it enables computer-intelligent full-process measurement, control, and monitoring.
