HRP 500.5Y.KO Mass Comparator
Mass comparators are used in calibration laboratories around the world. Their main task is to ensure the consistency of mass measurements and to verify weights according to the requirements of legal metrology. With the HRP 5Y.KO Manual Mass Comparator you can calibrate mass standards and weights according to OIML (R-111) recommendations for class F2 and lower classes. The HRP 5Y.KO mass comparators consist of a professional weighing platform and a 5Y weighing terminal. Inside the platform is an electromagnetic mechanism in a hermetic steel housing.

Self-Centring Pan – a Solution Straight to the Point
If you wish to minimise the effects of eccentricity on your measurement results, the self-centring pan is the answer. The use of the self-centring pan eliminates the error resulting from placing the weight “out of pan centre”. In addition, this solution allows the calibration of weights of different shapes and dimensions without the need to set the positioners for central loading of the mass standard each time. The purpose of the pan is therefore to stabilise and level non-centrally placed weights and to distribute several non-centrally placed weights as the resulting reference standard.
The self-centring pan is fitted at the manufacturing stage of the unit, so it must be ordered together with thee mass comparator (we do not sell it as a separate product). This is an extra cost option.
If you do not decide on the self-centring pan, you will receive a steel weighing pan featuring marks facilitating centric loading of mass standards.
