1.FEATURES OF GI-Series
The ionization gauge GI series consists of three following models.
①Metal Ionization Vaccum Gauge GI-M2
The Model GI-M2 is a hot cathode ionization vacuum gauge for pressure
measurement that uses the M type sensor head, which is smaller than that of the
predecessor model B-A type ionization gauge and consumes less power.
The measurable pressure range is 5.00 × 10
-8
to 9.99 × 10
0
Pa.( 3.70 × 10
-10
to 7.40
× 10-
2
Torr.)
The sensor head cable becomes the 150 degrees Celsius heat resistance
specifications by default.
②Ionization Vaccum GI-D7
It is a hot cathode ionization gauge to use a sensor head for used tetrode
transistor ionization gauge sensor head (WIT) and a sensor head for used B-A type
ionization gauge (WIB) for for many years.
③Ionization Vaccum GI-N8
It is a hot cathode ionization gauge to use a sensor head for used for tetrode
transistor ionization gauge.
It can measure a pressure range of 4.00 × 10
-9
to 6.00 × 10-
1
Pa.( 3.00 × 10
-11
to
5.00 × 10-
3
Torr.)
The degas method adopts an electron bombardment system method.
