WCJ Drill Cuttings Gas Desorption Index Calibrator is suitable for the inspection and calibration of various models of drill cuttings gas desorption instruments that use pressure sensing elements as detection probes. It is designed for the harsh production conditions in coal mines, where outburst prevention instruments are severely damaged during field use and require frequent inspection and calibration.

WCJ Drill Cuttings Gas Desorption Index Calibrator has the following functional features:
Direct reading of displayed data, clearly showing kPa and mmH?O values.
High precision, with a microprocessor capable of continuously correcting zero point and linearity.
Equipped with a self-contained micro-pressure generating device, manual pressure generation, with coarse and fine adjustment knobs to reduce the tension of compressed air.
