As the Swiss Designated Institute (DI) for hygrometry, MBW has responsibility for maintaining and improving the standards for humidity in Switzerland.
To achieve this, MBW continually improves methods of calibration by implementing new techniques to extend our range of capability and improve our published CMC (Calibration and Measurement Capability). We have implemented Primary Realizations for low and high range humidity generation (based on temperature and pressure). This has resulted in CMCs that compare favorably with the leading National Metrology Institutes worldwide.
Our CMC can be viewed here and at the Swiss Accreditation Service (SAS) website. As an accredited provider, MBW is regularly audited by external technical and quality assessors who regularly compare calibration with other NMIs or DIs.
