Vacuum gauge: An instrument used to measure less than atmospheric pressure based on atmospheric pressure.
Pressure vacuum gauge: An instrument used to measure greater or less atmospheric pressure based on atmospheric pressure.
Pressure vacuum gauges and vacuum gauges are used to measure the pressure or negative pressure of non-crystallizing, non-solidifying liquid, gas or vapor media without corrosion or explosive hazard to steel, copper and copper alloys.
The shockproof vacuum gauge is used to measure the negative pressure of non-corrosive and non-crystallizing media under vibration and pressure fluctuations.
Electrical contact pressure vacuum gauge and electrical contact vacuum gauge Copper and copper alloy no corrosion, no explosion danger of non-crystallized non-solidified liquid, gas and other media (pressure) and negative pressure. When the pressure reaches a predetermined value, the control circuit can be connected or disconnected with the help of a contact device, and an electrical signal can be sent at the same time.
Electric contact pressure vacuum gauge is used to measure the pressure and negative pressure of non-corrosive copper and copper alloy, non-explosive non-crystallized liquid, gas and other media. When the pressure and negative pressure reach a predetermined value, the magnetic electric contact device can connect or disconnect the control circuit
The electric contact vacuum gauge is used to measure the negative pressure of copper and copper alloys in non-corrosive liquids, gases or vapors. When the negative pressure reaches a predetermined value, it sends out an electrical signal to switch on or disconnect the control circuit.
Stainless steel vacuum gauge and stainless steel pressure vacuum gauge used for measuring stainless steel 316,316 L and 0Crl8Ni12MO2Ti non-corrosive liquid, gas medium pressure and negative pressure, all rust has a stronger corrosion resistance to the environment.
Acidproof pressure vacuum gauge is used to measure the pressure and negative pressure of nitric acid and alkali liquid medium; Acidproof vacuum gauge is used to measure the negative pressure of nitric acid and alkali liquid.
