SCS Calibration Laboratory

MBW is a by the Swiss Accreditation Service ISO/IEC 17025 accredited laboratory (SCS 0125) for humidity and temperature calibration. The uncertainties of our calibration are amongst the lowest available, and we provide fast turnaround times for the calibration of any type of hygrometer or thermometer.

Our laboratory in Switzerland has calibration systems based on both primary realizations and commercial humidity generators for calibration by comparison. Transfer standards are MBW373 dew point mirrors, SPRT’s and a triple point cell.  Our frost/dew point transfer standards are calibrated at a number of National Metrology/Designated Institutes including PTB, NPL, BEV and NIST. Through the ILAC mutual recognition structures, our calibration certificates are accepted and traceable worldwide.
