MBW Calibration

ROTRONIC UK is proud to be the UK distributor for MBW Calibration, the world’s leading manufacturer of chilled mirror hygrometers.

At the very highest level of measurement, National Standards Laboratories, MBW chilled mirror hygrometers are considered to be the most accurate, reliable and consistent humidity measurement technology available. They are a primary reference standard against which other sensors are calibrated.

As well as calibration laboratories, MBW chilled mirrors are used in meteorological applications, chemistry laboratories and throughout processing, manufacturing, engineering and storage industries across a dew/frost point range of -95°Cfp to +95°Cdp and pressures up to 200 bar.

    

New  MBW integration with Rotronic HygroGen2 – the lowest measurement uncertainties in portable temperature and humidity calibration

ROTRONIC has worked closely with MBW, to integrate their products into the HygroGen2 portable temperature and humidity calibration system. Particularly well suited is the MBW 473 Dew Point Mirror, whose RP2 measuring head is designed to be directly inserted into the working volume of the HygroGen2 chamber, and works across its full range. Temperature and humidity probes from all manufacturers can be calibrated with typical expanded measurement uncertainty at ambient conditions of less than 0.7 %rh. Download Application Note here.

New MBW T12 Multichannel Reference Thermometer 

The MBW T12 is a highly precise and stable platinum resistance thermometer (PRT) based multichannel temperature measurement system. Using a custom designed high quality measurement circuit, 24-bit analogue to digital converters and multiplexor sampling, the T12 provides 12 channels of low uncertainty temperature data for validation and calibration engineers. When used with an MBW chilled mirror, the accompanying PC software logs and plots live temperature and dew point measurements and calculates RH on the fly, providing the most versatile chamber validation tool available. See here for more details.

New MBW 973-CA Portable Chilled Mirror for Compressed Air Lines

Application specific versions of the MBW 973 are now available, which optionally include an internal sample pump, calibrated external PRT, and Peli transport case. The 973-CA is supplied with a choice of couplings and is adapted to plug directly into compressed air sample lines to make in-situ dew/frost point measurements. All versions include the Optimal Response Injection System (ORIS) for the fastest time to stabilisation at low frost points. See here for more details.

  5. MBW 973

    MBW 973

    The MBW 973 Dew Point Mirror is a portable chilled mirror hygrometer with an integrated measuring head for making spot-checks or continuous measurements of dew/frost point, pressure and temperature. Application specific options are available including internal sample pump and external PRT, and a choice of couplings for compressed air lines. Learn More
  6. MBW 973-SF6

    MBW 973-SF6

    The MBW 973-SF6 Analyzer was specifically designed for the measurement of humidity and SF6 purity in gas insulated switchgear systems. Humidity measurement data is displayed in ppmv, ppmw and dew/frost point at either system pressure or standard pressure. Purity measurement is displayed directly in % volume SF6, with addition SO2 concentration measurement. Both the humidity and purity measurements utilise accurate and reliable condensation techniques, and the integrated gas capture system ensures completely emission-free operation Learn More
