Dew Point Chilled
Mirror Hygrometers 

For Humidity Calibration, Measurement and Gas Quality Applications

Leading Experts in Humidity Measurement & Calibration Systems 

Accurately measure humidity or dew point on a temperature-controlled mirror surface

We are an ISO/IEC 17025 accredited SCS calibration laboratory delivering the highest, traceable accuracy in temperature and humidity | SCS Calibration Laboratory.  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 MBW™ 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.

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.

WHEN YOU NEED CLIMATIC CHAMBER VALIDATION

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. Explore our climate validation services.

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.
