ION Check System

The Ion Check is a complete solution to calibrate and compare high vacuum gauges. A spinning rotor gauge is used as a certified, accurate and long-term stable pressure standard. The ION Check is compact and optimized for this application, consists of an oil free and vibration insulated high vacuum system, a gas dosing unit for this pressure regime and a hard- and software to read out and calibrate vacuum gauges with analog output.

Spinning Rotor Gauge

How does the Spinning Rotor Gauge work?
The Spinning Rotor Gauge (SRG) system is comprised of a measuring head, a control/read out unit and a stainless steel measuring tube containing a 4.5 mm ball-bearing ball serving as the pressure sensor. Spinning Rotor Gauges are highly accurate, long-term stable and do not influence the pressure signal that is measured in any way (no temperature input / ionization / gettering / drifts etc.)
