Product Description

ZJ-27 hot cathode ionization gauge is now a commonly used wide range high vacuum ionization gauge, having the merits of wide measuring range, good stability, anti-oxidation, etc. Its

cover employs DM-305 glass, porcelain-metal for sealing






Major Technical Specifications

1. Measuring Range:1× 10 − 2 × 10 −5 Pa

2. Above earth potential of accelerating electrode: 225V

3. ove earth potential of Cathode: 25V

4. Above earth potential of collecting electrode: 0V


5. Emission Current: 100μA (100-10-1Pa), 1mA (10-2-10-5Pa)


Cautions for Operation

1.Check the vacuum degree to be no less than 5 × 10 −2 Pa before unsealing.

          2. Better be installed vertically.
