Swiss Engineering Takes Climatic Testing and Humidity Calibration to a New Level

MBW Calibration’s (Switzerland) recently launched 473-SHX dew point mirror was created to meet the criteria of climatic testing and humidity calibration over the range of most test facilities.

Incorporating a new micro engineered sample flow module that can work over the range -40…+125 °C, the instrument delivers temperature independent accuracy of ≤0.1°C dew/frost point.

The 473 dew point mirror can also be augmented with a 0.01% accuracy barometric pressure sensor and users have the option to add up to three additional Pt100 temperature sensors. These features ensure that effects, such as pressure variation and temperature uniformity, can be evaluated within a single instrument.

MBW is ISO17025 accredited for calibration of humidity and temperature, with uncertainties as low as ±0.03 K dew point (k=2), so their instruments can be delivered ready for immediate use in calibration or inter-comparison testing.
