Coal Mine Gas Desorption Analyzer DGC Type Downhole Desorption Instrument

Product Introduction of DGC Type Downhole Desorption Instrument for Coal Mine Gas Analysis
The DGC type downhole desorption instrument adopts the water displacement gas collection method, using the desorbed gas to displace the water column in the measuring cylinder. By reading the height of the gas column, it measures the gas desorption rate and desorption volume, and can also determine the desorbable gas volume. The gas desorption instrument has the following advantages: simple and compact structure, small size, lightweight, easy to transport and carry; low water consumption, suitable for field or underground operations, and ideal for water-scarce measurement locations; the gas desorption instrument is easy to level, requiring only a small flat surface or being hung up.
