Vacuum pressure gauge

Vacuum gauge: an instrument used to measure pressure less than atmospheric pressure on the basis of atmospheric pressure.

Pressure vacuum gauge: an instrument for measuring atmospheric pressure of greater than or less than atmospheric pressure.

Pressure vacuum gauge and vacuum gauge are used to measure the non corrosive action of steel, copper and copper alloys, no explosion risk of non crystallization, non solidification of liquid, gas or steam medium pressure or negative pressure.

The vacuum gauge used for seismic vibration and pressure fluctuation measurement, no corrosion, no crystallization of medium pressure.

Electric contact pressure vacuum gauge and electric contact vacuum gauge copper and copper alloy non corrosive effect, non explosive dangerous non crystal non solidified liquid, gas and other media (pressure) and negative pressure. When the pressure reaches a predetermined value, the control circuit can be switched on or off by using the contact device, and the electric signal is sent out simultaneously.

The electric contact pressure gauge is used to measure the corrosion free effect of copper and copper alloy, and the pressure and the negative pressure of gas and other media without explosion risk. When the pressure and the negative pressure reaches a predetermined value, the control circuit can be switched on or off by using the magnetic electric contact device.

Electric contact vacuum gauge for measuring liquid, gas or vapour pressure of copper and copper alloys. When the negative pressure reaches a predetermined value, the electric signal is sent out, and the control circuit is switched on or off.

Stainless steel vacuum gauge and stainless steel vacuum pressure gauge is designed to measure corrosive liquid that does not of stainless steel 316316L and 0Crl8Ni12MO2Ti, pressure and negative pressure gas medium, do not rust on the environment has stronger corrosion resistance ability.

Acid pressure vacuum gauge is used to measure the pressure and negative pressure of the liquid medium of nitric acid and alkali, acid proof vacuum gauge is used to measure the negative pressure of the liquid of nitric acid and alkali.

The main characteristics of vacuum pressure gauge are as follows:

(1) stable performance, high measuring accuracy, fast response.

(2) is an absolute vacuum gauge, the accuracy of 0.5 or more can be used as a standard vacuum in ten.

(3) measurement of the total pressure, including the pressure of gas and steam.

(4) the result of the measurement is not related to the type of gas, the composition and its properties.

(5) in the process of measuring m, the vacuum meter itself is very small, and it will not affect the atmosphere of being tested.

(6) there is no high temperature component inside the vacuum gauge, which will not cause the oil to break down.

(7) if the selection of corrosion resistant materials is made, the corrosion resistance of gas pressure can be measured.

(8) the structure is firm, and it is easy to seal and install.

(9) easy to operate, no need to adjust, but need regular check.
