We are internationally recognized as a leading developer and manufacturer of the high-quality MBW Calibration chilled mirror dew point hygrometers used in a variety of humidity calibration, measurement and gas quality applications. Most notably, our MBW instruments provide the calibration traceability for many laboratories such as humidity instrument manufacturers and National Metrology Institutes. Our MBW chilled dew point mirrors continue to be chosen as transfer standards for inter-laboratory comparisons both regionally and internationally.
We are a leading manufacturer of the MBW Calibration SF6 gas quality 973 Model Dew Point Mirror Hygrometer which was designed uniquely on chilled mirror technology that provides years of high precision and high stability measurements without frequent sensor replacement.
Our MBW chilled mirror condensation technology provides highly precise, stable, and repeatable results. Water vapor condenses onto a temperature-controlled mirror surface and this ‘dew point’ is detected with advanced optical electronics. Since dew point is specific to water vapor concentration and not temperature dependent, measurement precision is consistent across the full application range including high temperature and humidity conditions in climatic test chambers.
Our MBW chilled mirror hygrometers 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 MBW chilled mirrors are used by national standards and accredited laboratories worldwide.
Our MBW 473 Model Dew Point Mirror Hygrometer transfers reference standard performance into applications such as climatic chamber validation, relative humidity calibrators and a wide range of industrial processes.
Our MBW 573 Model Dew Point Mirror Hygrometer is a high performance 19” rack format instrument with an integral measurement head, pressure sensor, sample pump and flow meter for continuous precision monitoring of frost/dew point and absolute humidity values across a wide range of applications.
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. 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. 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.
Measurement of temperature uniformity is the most important measurement when calibrating or validating climatic chambers. It is also typically the largest uncertainty contribution. The MBW T12 is a high precision multi-channel thermometer that is suitable for measurement of temperature uniformity in climatic chambers. It is combined with specially performance Pt100Ω platinum resistance thermometers (PRT) that are compact, precise and stable.
