Liquid column balanced piston pressure gauge


Liquid column balanced piston pressure gauge (liquid column balance)


Technical indicators:

Model: YY0.4, YY0.7

Measurement range (MPa): YY0.4: -0.1 to 0 to 0.4; YY0.7: -0.1 to 0 to 0.7

Accuracy level: 0.005

Piston material: tungsten carbide

Weight material: stainless steel

Uses: can be used as a working benchmark and high precision measurement


Technical features:

● 0.005 pressure gauge is equipped with a thermometer for temperature correction

● The pressure measurement can start from zero, and can measure negative pressure and positive pressure. It has the advantages of high sensitivity, high accuracy, wide measuring range and very small piston falling speed.

● The piston and piston tube are made of hard alloy tungsten carbide, which is wear-resistant and has a long service life.

● There is a displacement sensor to indicate the working position of the piston, and the reading is convenient and correct.


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