ZJ-12 vacuum gauge

Zj-12 ultra high vacuum ionization gauge is a kind of ionization gauge widely used in China at present. The gauge has compact design, simple structure, low power consumption, easy to degasses, stable and reliable measurement, wide range. In terms of service life, the regulator USES double filaments, which greatly increases the service life of the regulator. When one filament burns out, the other filament can be replaced immediately without affecting the normal use of the user. The other is the metal DN35CF flange.
