Overview

Maximum capacity [Max]: 5.1g
Readability [d]: 0.0001mg

Mass comparators of UMA 5 series stand for the highest standard of professional automatic

mass

comparators.
They provide comparison of 1 mg – 5 g weights of E1 and lower classes.
The device is equipped with 36 magazine positions allowing to deposit up to 36 weights. This solution allows to perform either comparison for complete set of weights carried out within one process or comparison for just a few weights of the same mass.
Owing to elimination of human factor and with temperature changes and air drafts reduced to zero, UMA automatic

mass

comparators provide the highest possible measurement repeatability.
