JB/T 599-2005 Pressure Calibration Device

Characteristic Introduction

• The entire system is designed without one-way valves, completely eliminating the problems of easy blockage, leakage, and malfunction of one-way valves;

• It can simultaneously calibrate pressure instruments with the same range, as well as pressure instruments with different ranges;

• Each output has a shut-off valve, which can perform a sealing test on the tested instrument;

• Spiral pressure rise and fall, stable pressure rise and fall, easy to operate for return calibration;

• Open structure, convenient for cleaning and maintenance;

• A hydraulic source that can be evacuated.
