General Purpose Type
Ionization Gauge
GI Series
GI-M2
ULVAC
This series is hot cathode type ionization vacuum gauge, capable of measuring pressure in the 9.9 to 5 x 10-8 Pa (7.4 x 10-2 to 3.75 x10-10 Torr, 9.9 x 10-2 to 5 x 10-10 mbar)(Metal gauge, GI-M2), 6.7 x 10-1 to 10-6 Pa (5 x 10-3 to 9.75 x10-9 Torr, 6.7 x 10-3 to 1.3 x 10-8 mbar)(Glass gauge, GI-D7) range using triode tube or B-A type sensor heads
Features
- Can measure a wide pressure range from 9.9 to 5×10-8Pa (GI-M2)
(7.4 x 10-2 to 3.75 x10-10 Torr, 9.9 x 10-2 to 5 x 10-10 mbar) - 2 types vacuum tube, metal and glass: Sensor head selected depending on the application (bare type also available)
- Small-sized metallic sensor head prevents it from breaking (GI-M2)
- Sensitivity setup can be changed for different gases. Allowing even more accurate pressure measurement.
- Ideal for fixing the measurement range
- 2 set points output
- Switch 1/2 filament, sensitivity setting, range hold function, Degas function
- RS232C communication
Applications
- Vacuum heat treatment furnace
- Vacuum brazing furnace
- Vacuum evaporation system(diffusion pump type)
- Process control for furnaces and other industrial equipment
