Precision Pressure Gauge general pressure gauges, precision pressure gauge can also be in the process of site accurate measurement of copper alloy and alloy structural steel and other materials, non-corrosive, non-crystalline, non-solidified medium pressure used to validate industry. 
 Precision Pressure Gauge mirror ring (type A, type B) in the scale line more clear and precise readings in use. With zero device (B) 


 ■ structural principle: 
 Precision pressure gauge pressure measurement system, transmission, indicating devices and housings. Elastic component of precision pressure gauge manometry special treatment, precision pressure gauge is stable and reliable performance, and high-precision drive mechanism supporting debugging, to ensure the accurate instructions accuracy. 
 Precision pressure gauge working principle is: the measured media pressure acting on the elastic element to produce elastic deformation - displacement amplification transmission rod driven by the indicating device indicates the measured pressure.
