precision pressure vacuum gauge
The so-called precision pressure vacuum gauge is the amount of field work across a vacuum of high-precision pressure measuring instrument, which can measure Positive pressure, negative pressure is also measured pressure, especially suitable for verification or confirmation normal pressure such as pressure and vacuum gauge negative pressure associated process instrumentation.
