The vacuum pressure gauge is an instrument that is used to measure more than and less than atmospheric pressure based on atmospheric pressure.
Shock-proof vacuum pressure gauge as a classification of shock-proof pressure gauge, used to measure the negative pressure of non-corrosive, non-crystalline media under vibration and pressure fluctuations.
Electric contact vacuum pressure gauge and electric contact vacuum gauge Copper and copper alloy no corrosion, no explosion risk of non-crystalline non-solidified liquid, gas and other media (pressure) and negative pressure.
Stainless steel pressure vacuum meter is used to measure the pressure and negative pressure of liquid and gas medium without corrosion effect on stainless steel 316,316L and 0Crl8Ni12MO2Ti. All stainless steel has stronger corrosion resistance to the environment.
Acid pressure vacuum meter is used to measure the pressure and negative pressure of nitric acid and alkali liquid medium; The acid-resistant vacuum gauge is used to measure the negative pressure of nitric acid and alkali liquids.
