This product is an auxiliary equipment in pressure instrument testing and can improve work efficiency when calibrating pressure gauges in the laboratory or on site. Complete pressure instrument calibration and testing.

The lever drives the large-capacity chamber piston to reciprocate, generating pressure or vacuum. The pressure or vacuum is output through the switch and reaches the fine-tuning and pressure output interface through the pressure stabilizing valve. Supplemented by designed fine-tuning, quick interface, and pressure stabilizing valve. With the advantages of simple operation, reasonable structure and good sealing performance, it can be widely used in measurement, scientific research, industrial and mining enterprises, instrument manufacturing and other industries.
