As a Swiss Designated Institute (DI) for hygrometry, we have a responsibility for maintaining and improving the standards for humidity in Switzerland. To achieve this, we continually improve 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 at the Swiss Accreditation Service (SAS) website.  As an accredited provider, we are regularly audited by external technical and quality assessors who regularly compare calibration with other NMIs or DIs.  

An essential part of our role as the Designated Institute for humidity is fundamental research. This activity is driven by the necessity for continual improvement in our knowledge, the reduction in our measurement uncertainties, and specific requirements from our customers and business partners.  Our in-house research laboratory is equipped with humidity and temperature generation equipment that compares with the very best laboratories around the world, so we are able to replicate operational conditions that mirror our customers activity. In combination, we have a comprehensive range of analytical equipment that enable us to thoroughly investigate cause and effect.

As an example, we are able to photograph and video condensation formation on the chilled mirrors in our transfer standard mirrors. This has enabled us to solve issues where interference effects have increased measurement uncertainties in certain scenarios.

Climatic chambers are in widespread use across many industries. They are used to simulate climatic conditions including temperature, humidity, pressure, vibration and light intensity. Conditions must be controlled and varied according to user or test specifications. Our MBW products can provide the simulation of climatic conditions including temperature, humidity, pressure, vibration and light intensity.  You can find our products in automotive component test chambers, pharmaceutical stability chambers, calibration test chambers, and military electronics testing.

Climatic chambers are in widespread use across many industries. They are used to simulate climatic conditions including temperature, humidity, pressure, vibration and light intensity. Conditions are controlled or varied according to user or test specifications. Products and samples are placed within the controlled environment according to defined test specifications that require certain conditions to be maintained. Examples include 40 °C / 75 %rh for drug stability and 85 °C / 85 %rh for electronic component testing. Confirmation that the correct environmental conditions have been achieved is a pre-requisite for compliance with the respective standards that apply in each industry.
