Intended Use

The Compact Cold Cathode Gauge IMG-500 has been designed
for vacuum measurement of gases in the pressure range of
-9
2×10
The gauges can be operated in connection with an Agilent
Vacuum Gauge Controller AGC-100, an Agilent Turbo AG Rack
Controller, or with another controller.

Functional Principle

The gauge functions with a cold cathode ionization measure-
ment circuit (according to the inverted magnetron principle).
Over the whole measurement range, the measuring signal is
output as a logarithm of the pressure.
