QINGDAO LONGJIE APPARATUS LIMITED COMPANY

Average pressure gauge series:

pressure gauge(Y-□)
Usage: This instrument is used to test the liquid or gas pressure which all have no corrosion to coppper alloy, no explosion, and no crystalization and precipitation.
vacuum pressure meter(Z-□)
Usage: measure the vaccum degree of liquid and liquid (negative pressure)
Vaccum pressure meter(YZ-□)
Usage: This meter is used to measure the pressure and vacuum degree of gas and liquid.
