What is a general pressure gauge?

General pressure gauges are used to measure the pressure of gases, vapors and liquids that do not corrode copper and copper alloys.

In general, the components of the pressure gauge that mainly contact the working medium under test (such as joints and spring tubes) are made of copper and copper alloys. It has good anti-corrosion and anti-rust properties.

 The highest precision of a general pressure gauge is level 1.

General pressure gauges include pressure gauges, vacuum gauges and pressure vacuum gauges.

 What is a precision pressure gauge?

Precision pressure gauge refers to a pressure gauge or vacuum gauge with accuracy level equal to or higher than 0.4.

Precision pressure gauges are manufactured using higher quality materials and fine craftsmanship.

The precision pressure gauge can be used as a standard for verifying general pressure gauges, and can also be used for high-precision pressure measurement.
