Mass comparators of RADWAG design allow comparison of mass standards in accordance with OIML R111, from 1 mg to 50 kg in class E1, and up to 2000 kg in class F2.
Wide range of RADWAG products comprises manual, automatic and
vacuum mass comparators, comparator for determination of density and volume,
robotic mass comparators, all representing the highest level of comparison process automation.
An important stage of the comparison is determining magnetism of mass standards. This enables to unequivocally determine whether mass measurement is burdened with an error connected with mass standard magnetic characteristics or results from damage of a measuring device. The OIML R111 indicates susceptometers as a reference method for determination of magnetic susceptibility and polarisation of mass standards.
