Description
Reviews

Introduce:
1. The ZJ-12 super-high vacuum ionization gauge is a widely used ionization gauge. The gauge has a compact design, simple structure, low power consumption, easy degassing, stable and reliable measurement, and a wide range.

2. In terms of service life, since the regulator uses dual filaments, this greatly increases the service life of the regulator. When one of the filaments is burned out, the other filament can be replaced immediately without affecting User's normal use

3. Structure: DM-305 is adopted, the connection size is 19±0.2MM or glass and metal sealing; the other is metal DN35CF flange

4. There are many models, not all of them can be displayed, accept customization

Technical parameters:
1.Measuring range: 1X10^-1---5X10^-8Pa
2.Above earth potential of accelerating electrod: 200V
3.Above earth potential of cathode: 50V
4.Above earth potential of collectrode: 0V
5.Emission current: 4X10^-4A、4X10^-3A
6.Gauge constant: 7.5X10^-2Pa^-1±20%
7.Electron bombardment Exhaust: max power to be 30W
8.Roase temperature: 400℃

Cautions for operation:
1. Check the vacuum degree to be no less than 5X10^-2Pa before unsealing
2. Better be connected vertically
3. Keep in vacuum condition for long time unuse
4. Vacuum degree should be no less 5X10^-3Pa Pa in case of gauge exhause
5. For bett ultimate vacuum degree, the gauge must be roasted together with the system.
