Spinning Rotor Vacuum Gauge Transfer Standard
Overview
The Spinning Rotor Gauge is a high-vacuum gauge that operates by measuring the amount of viscous drag on a magnetically-levitated spinning ball, which is directly related to the number of molecules in the chamber. It is commonly used for calibration and metrology of other high-vacuum gauge sensors such as cold cathode and hot-filament ionization tubes. Its accuracy specification of 1% of reading is guaranteed over the range of 1 x 10-2 Torr (mbar) to 5 x 10-7 Torr (mbar).
- Transfer standard for calibration in 10-2 to 10-7 Torr vacuum range, DKD traceable
- Overall measurement range up to 1 Torr/mbar (with reduced accuracy)
- Insensitive to ionization effects from other vacuum gauges
- Stainless steel wetted surfaces
- Multiple outputs such as RS232, USB, high-resolution analog, and discrete trip relays
- CE and RoHS compliant
