The HRP 5Y.KO series of mass comparators enables calibrating mass standards and weights in accordance with OIML Recommendation (R-111) for class F2 and lower classes.

Comparators are used to ensure consistency in mass measurements as well as to verify weights according to legal metrology requirements. RADWAG mass comparators have been recognized by calibration laboratories in many countries.

The HRP 5Y.KO mass comparators consist of two elements: a professional weighing platform (modern design of an electromagnetic mechanism in a hermetic steel casing) and 5Y terminal. The weighing platform is made of steel and features marks facilitating centric loading of mass standards.

The comparator is equipped with a self-centring weighing pan, which significantly minimises the influence of eccentricity during measurements. The self-centring weighing pan eliminates the error of placing the weight "out of pan centre". This solution also enables calibrating weights of different shapes and dimensions without the need to set the positioners for central loading of the mass standard each time.

The comparator has a user-friendly menu.

Data security and work results archiving are ensured by RADWAG terminal software.
