WAY.4Y.KO Manual Mass Comparators




The newest line of Mass Comparators enables adjusting mass standards and weights according to the OIML recommendations (R-111) from 1 mg to 5 kg for E1 class and lower.

Mass comparators are used both for ensuring traceability of mass measurements, and verification of weights in accordance with the principles of legal metrology. Mass Comparators have gained recognition among Accredited Calibration Laboratories in many countries.

Mass comparator WAY 4Y.KO series similarly to other models, comprises two components. One of them holds the electronic module, and the other precise mechanical measuring system.
The WAY 4Y.KO series comes standard with an aesthetic, large weighing chamber with glass anti-draft shield. All elements of the weighing chamber are manufactured from glass or metal to minimize the influence of electrostatic charges on weighing result. Mass comparator WAY 4Y.KO series features an intuitive menu supporting a user while operating the instrument.
