Ionization vacuum gauge correction coefficient test.
- Measurement range: 10 Pa to 1E-5 Pa (possible to use it in combination with the Pirani vacuum gauge and the atmospheric pressure sensor)
If diaphragm vacuum gauge indicated pressure would be considered as true value due to it's resistance to gas, then difference between a true value and ionization gauge indicated pressure with correction turned on would be 59,5%.
The price of the G-TRAN Series "Multi ionization Gauge SH2" combined vacuum gauge will be 120,000 yen for the SH2 Multi ionization gauge unit for measurements between the medium and high vacuum range, 180,000 yen for the SH2 and SPU Pirani gauge connection type that can measure from low to high vacuum range, and 230,000 yen for the type which includes the SH2, SPU and SAU pressure sensor that can measure from the atmospheric pressure to high vacuum range.
The CVM series vacuum gauge module with on-board electronics/controller is based on the convection vacuum gauge principle.
In recent years, several vacuum gauge manufacturers have introduced gauge systems that approximately span the 0.1 mtorr to 1,000 torr range, allowing users to follow their rough pumping activities from atmosphere without resorting to multiple gauges.
Dual-Sensor Vacuum Gauge. The Model 2002 dual-sensor vacuum gauge from Hastings Instruments (800-950-2468) is a wide-range vacuum instrument that provides accurate measurements over seven decades of pressure from [10.sup.-4] torr to 1000 torr.
The CVM series vacuum gauge module with on-board electronics/controller is based on the convection vacuum gauge principle, and it measures pressures from 1000 to [10.sup.-4] Torr.
This article is excerpted from a more detailed version containing an extensive list of vacuum gauge experts you can contact for further information.
The CVM series vacuum gauge module, also known as an active gauge or transducer, is based on the convection vacuum gauge principle.
"When we turn on our hot cathode vacuum gauge (which usually has not been used for some time), we find that we have a higher baseline pressure than we should.
