Product Description

ZJ**4D Metal thermocouple vacuum gauge tube for vacuum metalizng machine measurement/ZJ**4D vacuum gauge for sale

This type of vacuum gauge adopted smaller thermal capacity nickel chromium - constantan as a heating wire and thermocouple wire with stabilizing treatment. With automatic enviroment temperature compensation and dust protection, has a simple structure, wide range, fast response, anti-pollution, anti-oxidation, small drift, long life, stable performance,reasonble  price and so on. Especially for low vacuum measurement. This type of vacuum guage can be used with the ZJ**3 glass thermocouple regulated interchangeable.
