Structure:
This guage is made up of the measuring system, gear setting, pointing setting and the outer case. The flexibility parts is dealed with the special technics, which makes the operation reliable. With the use of the high accurate gear setting , it can be assured the high pointing accuracy .The principle of  the accurate pressure guage :The pressure of service medium acts on the flexibility parts and make it moved, with the help of the stick, magnified by the gear setting, and the pointer point it out on the dial.

Main Technology Data:
Environment condition: 5-40, relative humidity is no more than 80%, and the undulate of the shock and pressure resource has no influence on accurate readings of the gauge.
Temperature influence: If the environment temperature from 20-+3(A type) or 20-+2(B type ), must consider the additional error is about 0.4%/10%.
