Portable hydraulic pressure source is an important auxiliary equipment in the testing work of pressure instruments. It is used in conjunction with pressure standards to complete the calibration and testing of pressure instruments. It is easy to carry, not easy to leak, and requires less maintenance. It is mainly used for on-site or laboratory calibration of pressure (differential pressure) transmitters, precision pressure gauges, pressure sensors, pressure switches and other pressure instruments to provide stable pressure.

The pressure pump uses a high-quality hydraulic pump as the pressure generating part, supplemented by an exquisitely designed fine-tuning, quick interface, and pressure-stabilizing valve. The advantages of simple operation, reasonable structure, good sealing performance, wide range pressure generating system, can be widely used in measurement, scientific research, industrial and mining enterprises and instrument manufacturing and other industries.
