PM 25.4Y.KB Mass Comparator


Maximum capacity [Max]: 25,5kg

Readability [d]: 10mg

For adjusting mass standards and weights according to the OIML recommendations (R-111) from 1 kg to 50kg for F2 class and lower.

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

Mass comparator PM 4Y.KB series comprises two components. One of them holds the electronic module and the other a precise mechanical measuring system.
The high measuring accuracy is guaranteed by a semi-automatic adjustment system with external mass standards. The weighing pan is made of aluminum and features holders for centring the tested mass standard. The PM 4Y.KB series features an intuitive menu supporting a user while operating the instrument.
