GAMMA IONIZATION CHAMBER WITH CHECK
VOLUME
The KG 80 ionization chambers have a second electrode
system within the pressurized housing.
The second system is irradiated by a built-in beta source,
which generates a continuous detector current for test
purposes.
This test current can be added to the current of the
measuring system by an external switch unit, which is
part of the NV 102 P c/f-converter.
