  Product Description 

vacuum  pressure gauge

Vacuum gauges used in machinery, petroleum, chemical, metallurgy, mining, electricity and other sectors, the measurement of steel, copper and copper alloy corrosion-free, non-explosive without crystallization pressure liquid, gas or vapor medium or not solidified negative pressure.

vacuum  pressure gauge  structural principle:

1. vacuum system is composed of pressure gauges, gear drive mechanism, showing the number of devices and the shell formed.
2 .vacuum gauge shell airtight structure, can effectively protect the internal parts from the environment and contamination intrusion.

3 .gauge filled damping fluid in the housing (typically silicone oil or glycerol), anti-vibration environment can reduce media pressure pulsation and influence.

vacuum  pressure gauge  main features:

     (1)Stable performance, high accuracy, fast response.
     (2) is an absolute vacuum gauge, precision above 0.5 can be used as a standard vacuum in ten use.
     (3) measures the total pressure, including gases and vapors.
     Nothing to do with the type of gas results (4) measurement, composition and properties.
     (5) m during measurement, vacuum suction and discharge gas meter itself is small, the test does not  affect the atmosphere.
     (6) No hot parts inside the vacuum gauge, does not make the oil vapor decomposition.
     (7) if the choice of corrosion-resistant materials manufacturing, measurable corrosive gas pressure.
     (8) solid structure, and easy to seal and installation.
     (9) simple, without adjustment, but require regular calibration

Each unit has individual box and all boxes are packed in standard packages
