High Accuracy Precision Pressure Gauge

Short Description:

Product Detail

Product Tags


Precision pressure gauges are mainly used to calibrate general pressure gauges and to accurately measure the pressure of liquids, gases and vapors that are not corrosive to copper and its alloys. It can also be used to calibrate or verify other pressure measuring instruments as well as other types of instruments whose display value has a certain functional relationship with pressure value.


The precision pressure gauge is composed of a measuring system (joints, Bourdon tube, etc.), a transmission system (pull rod, gear transmission mechanism), indicating parts (pointer and dial) and a casing (case, ring and glass). Its elastic elements are treated with a special process, combined with dedicated movement components.

When the pressure of the measured medium acts on the elastic element, the elastic element deforms and moves, and the transmission system is driven by the pull rod, so that the indicating device indicates the pressure on the dial

■Please read the instructions carefully before use.
■The pressure gauge should be installed horizontally or vertically.
■ Please use Hakin special medium pressure gauge when measuring the medium that is explosive or corrosive,easy to crystallize or solidify.
■If the influence of ambient temperature deviates from 20+3°C, the additional temperature error of 0.4%/10°C must be considered.
