This is an ionization vacuum gauge ball for pressure measurement between 100Pa and 10-2Pa.
LG-11S uses thoria coated iridium filament to provide low operating temperature and extended product life. The connection with the vacuum equipment uses a φ15 adapter or is glass sealed to a glass adapter with φ70 ICF.
This is a sealed glass tube type B-A ionization vacuum gauge measurement ball for pressure measurement in the range under 10-2Pa.
UGD-1S is a Kovar glass sealed B-A gauge. The grid is made of tungsten and degassing is performed by electrical heating. Therefore, pressure can be measured even during degassing.
This is a B-A gauge with the high pressure end measurement range expanded. Degassing is performed by grid electrical heating similar to UGD-1S. A thoria coated iridium filter is used to enable high pressure measurement.
The connection with the vacuum equipment uses a φ15 adapter or is glass sealed to a glass adapter with φ70 ICF.
This gauge directly mounts a B-A type electrode on a flange. This is directly attached to the equipment making it suitable for ultra-high vacuum measurement without error due to feed through. Platinum-clad molybdenum wire is used for grid to minimize error due to gas contamination.
NIG-2F uses tungsten filament. In addition, NIG-2TF uses yttria coated filament which lowers the operating temperature, suppresses degassing, and improves ultra-high vacuum measurement.
This gauge can be used from atmospheric pressure and is installed with φ15 adapter. A Pirani gauge that can be baked at standard heatproof temperature of 80℃ is also available (200℃ maximum heating temperature with connectors removed)
This gauge can be used from atmospheric pressure and is installed with φ15 adapter. (150℃ maximum heating temperature with connectors removed)
