Mass comparators of UMA 1000 series stand for the highest standard of professional automatic mass comparators.
They provide comparison of 100 g – 1000 g weights of E1 and 10 g - 1000 g weights of E2 and lower classes.
The device is equipped with 18 magazine positions allowing to deposit up to 18 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.

Repeatability is expressed as a standard deviation determined for 6 ABBA cycles. Standard deviation is experimentally determined under ambient conditions for calibration of E1 class mass standards specified in OIML R111 (Table C.1.) document.
