Abstract
METAS designed and developed a new instrument for calibrating microforce sensors in the range of 1 nN to 60 mN. The calibration is realised by means of electromagnetic force compensation of a balance and traceable to the SI unit of mass. The expanded measurement uncertainty (type B) of our measuring apparatus is 0.125 μN (absolute) and 2400 ppm (relative). Our measuring apparatus was verified in a bilateral comparison between METAS and PTB. The degrees of equivalence are in excellent agreement between the two institutes.
