MKS Instruments Unveils a New Approach to Pressure Measurement at the AVS International Symposium
In its collaboration with NIST, MKS is pleased to announce that it will present, for the first time, a prototype version of its innovative and compact, photonics-based pressure standard at the AVS 65th International Symposium and Exhibition,

One of NIST’s missions is to develop primary standards based on the principles of quantum mechanics, and they have achieved this goal through their fixed length optical cavity (FLOC) invention, incorporated into a laser-based measurement system that measures the speed of light in any gas as compared to that in vacuum. With a higher resolution in the ability to measure pressure changes, the FLOC-based system significantly outperforms the traditional mercury standard, yielding more reliable measurements, while reducing cost. Additionally, in an effort to develop this technique into a commercial product, MKS and NIST have cooperated in the development of an innovative laser-based measurement system that is both portable and transportable. It is at least 20 times smaller than the typical mercury column manometers used as primary pressure standards. Moreover, it is mercury-free and therefore environmentally friendly.
“MKS Instruments brings over 50 years of pressure measurement, optical and laser experience, and we are a perfect complement to NIST and their capabilities. MKS is honored to have been selected by NIST to work with them on this important and prestigious development,” said
