About us
ph-instruments was founded in 2018/19 by Peter Hofmann after a 19-year career at MKS Instruments. He had positions as Sales-& Application Manager DACH, France, and Benelux, finally and for 10 years as Managing Director for Continental Europe.
The business idea to go for the Spinning Rotor Gauge Technology is simple: An outstanding concept for vacuum pressure measurement in industrial High Vacuum applications.


The unique 2 part sensor/readout design allows a robust, accurate, reliable, contactless, and long-term stable vacuum measurement of static and dynamic vacuums. ph-instruments partners with other independent companies that offer unique technologies to measure the pressure from the atmosphere to a high vacuum. The inventor of the SRG Technology, the long-time R&D and manufacturing manager of SRGs, and the sales/application manager of digital vacuum gauges built the core team.
