    Classification

    ● Thermocouple gauge

    ZJ-54DThermocouple gauges are mainly used for low vacuum measurement.

    ● Hot cathode gauge

    ZJ-10 series and ZJ-27 series hot cathode gauges are mainly used for high vacuum measurement.

     

    Features

    ● ZJ-54D thermocouple gauge has the characteristics of simple structure, wide measurement range, fast response, anti-pollution, oxidation-resistivity, small drift, long service life, stable performance.

    ● ZJ-10 and ZJ-27 hot cathode gauges has typical triode box structures. Adopting noble metal oxides cathodes, they have the features of oxidation resistance, instantaneous atmospheric impact resistance, stable performance and long service life.

     

    Application

    Vacuum gauge is mainly used for vacuum measurement of vacuum environment such as vacuum coating, solar collector tube manufacture, vacuum smelting, etc.
