The Cetron CE8130
ionization gauge is a flange mounted Bayard-Alpert (BA) type, which
has a range of 1 x 10-3 Torr to 2 x 10-11 Torr. It is available with either
a two thoria coated iridium filaments (CE8130)
or two tungsten filaments (CE8130T).
Both filament types are replaceable.
The Cetron CE8140
is a high sensitivity ionization gauge that has a range of 1 x 10-3 Torr
to 4 x 10-10 Torr. It incorporates a replaceable bonded thoria filament and
is well suited for either electron bombardment or I2R methods degassing,
making it compatiable with either type of controller.
