The dynamic viscosity (mPa.s or cP) of liquids is measured using a rotational viscometer. Calibration Lab is your partner for the calibration of all types and models of rotational viscometers. Certified measurement equipment and NIST traceable standards are used for calibrating your instruments, assuring the user of the correct functioning and accurate measurement results. Brookfield instruments are being calibrated and controlled using a master viscometer, while instruments from other brands (ThermoHaake, Fungilab, Rheotekâ€¦) are calibrated using certified standards. Our service engineers calibrate your viscometers on site or in our own calibration laboratories.
