Too many operations spend time chasing moisture readings they do not fully trust. Repeated calibrations, inconsistent measurements, and uncertainty. When process conditions become critical, uncertainty is not just frustrating. It is expensive.

Full process confidence starts with knowing the moisture value is correct. That is why our chilled mirror measurement technology remains the trusted gold standard for precision humidity and moisture analysis. Instead of relying on inferred values, chilled mirror technology delivers direct, drift-free measurement you can trust when accuracy matters most.

Gold Standard in Hygrometers and Calibration Service
 Reliable and accurate moisture measurements
 Drift-free performance
 High precision for demanding applications
 Confidence in every result

We are an ISO/IEC 17025 accredited calibration laboratory delivering the highest, traceable accuracy in temperature and humidity. As an internationally recognized leading manufacturer of high-quality dew point chilled mirror hygrometers used in a variety of humidity calibration, measurement and gas quality applications, our instruments provide the calibration traceability for many laboratories such as humidity instrument manufacturers and National Metrology Institutes.  Our chilled dew point mirrors continue to be the transfer standard for inter-laboratory comparisons both regionally and internationally.

Don’t compromise on accuracy – choose our point chilled mirror hygrometers for your humidity calibration, measurement, and gas quality applications. Ensure precise data, maintain compliance, and safeguard your operations with the gold standard in humidity measurement.  Let us know if have any specific requirements.  We’d love to help!

Our MBW chilled mirror analyzers have a typical service life of more than 15 years thanks to the use of high-quality materials and Swiss precision engineering. The high-quality platinum resistance thermometer (PRT) element embedded within the mirror ensures excellent long-term measurement stability. Thanks to the precise dew point and temperature measurements as well as the stability and long service life, our chilled mirrors are used by national standards and accredited laboratories worldwide.

Our chilled mirror analyzers typically offer high accuracy, repeatability, and sensitivity, as well as low maintenance requirements and a wide measurement range. They are also suitable for measuring the dew point temperature of various gases, including compressed air, natural gas, and industrial gases, as well as for measuring the frost point temperature of refrigerants and other low-temperature fluids.
