ZJ-10B ionization vacuum gauge has the merits of anti-oxidation, low filament working temperature, good linearity, etc. and is a kind of middle-vacuum gauge suitable for operation under high pressure.
Its cover employs DM-305 glass, porcelain-metal (naked gauge) for sealing.
Major Technical Specifications:
| Type | ZJ-10B | | Measuring Range | 6.5*101～2*10-4Pa | | 6.5*10-1～2*10-6mbar | | 4.87*10-1～1*10-6Torr | | Gauge Constant | 0.15 +- 15 % Pa-1 | | 0.0015 +- 0.015 % mbar-1 | | 0.0011+-0.011% Torr-1 | | Operation Parameters: | | | Above Earth Potential of Accelerating Electrode | 165 V | | Above Earth Potential of Cathode | 50 V | | Above Earth Potential of Collecting Electrode | 0 V | | Emission Current | 50μA （0.65 ～10-4mbar） | | 500μA（10-5～10-6mbar） | Cautions for Operation:
1. Check the vacuum degree to be no less than 5*10E-2Pa before unsealing.
2. Install as vertical as it can.
3. Vacuum degree should be no less than 5*10E-3Pa in case of gauge exhaust.
4. If the naked gauge is not used for a long time, keep in vacuum condition.
