Technical features:

● Due to the high sensitivity of the lower limit of the pressure gauge, the accuracy at the lower limit is also 0.01 level, ±0.01%. It has the advantage of "wide range".

● Both the piston and the piston cylinder are made of tungsten carbide material and polished by special process, which not only has small temperature error, but also has small piston falling speed, long free rotation of the piston and long service life.

● The upper limit is more than 25MPa pressure gauge, the working medium is di(ethylhexyl) sebacate, the viscosity is 20-25mm2/s at 20 °C, the sensitivity of the pressure gauge is greatly improved; the working medium transformer below 25MPa Oil and kerosene mixed oil.

● The weight is directly attached to the piston through the hanging basket, which avoids the additional vertical force brought by the ball bearing device and the sliding bearing device. At the same time, the center of gravity of the weight makes the pressure gauge run smoothly at the bottom end of the piston, and the indication value is accurate.

● The piston's up and down stroke is ±1.5mm. It is displayed with displacement sensor and instrument, which is sensitive, eye-catching and accurate.

The certificate of China Institute of Metrology or Shanghai Metrology and Testing Institute is attached to the factory.
