CWC3 Portable Multi-Parameter Measuring Instrument for Gas Extraction Pipelines

The CWC3 Portable Multi-Parameter Measuring Instrument for Gas Drainage Pipelines is a portable mining intrinsically safe instrument with an explosion-proof mark of Exib I. It can measure parameters including gas flow rate, gas concentration, and pipeline negative pressure, as well as the mixed gas flow rate and pure methane flow rate in drainage pipelines. All measured data can be stored, displayed, and printed. The instrument features automatic power-off protection and an under-voltage indicator. It has a large data storage capacity, capable of storing 100 sets of comprehensive measurement data and 300 sets of single-parameter measurement data. The CWC3 Portable Multi-Parameter Measuring Instrument for Gas Drainage Pipelines is designed and manufactured in accordance with MT/T 642—1996 "Technical Conditions for Comprehensive Parameter Measuring Instruments for Pipeline Gas Drainage" and relevant provisions of GB 3836-2000.
