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 PS 4Y.KB series comprises two components. One of them holds the electronic module, and the other precise mechanical measuring system.

The comparator features an aesthetic, large weighing chamber and a glass draft shield in one with opened side and top door. All elements of the weighing chamber are manufactured from glass or metal to minimize the influence of electrostatic charges on weighing result. The PS 4Y.KB series features an intuitive menu supporting a user in instrument operation.

  • Effective and Excellent MeasurementThe PS.4Y.KB mass comparator represents the standard-class manual mass comparators. The comparator allows to compare weights of class F2 and lower of mass ranging between 100 g and 1 kg.
  • Maximum Comfort of Operation The PS 4Y.KB is comprised of two parts. One featuring an electromagnetic module, the other a precise mechanical measuring system. The mass comparator is equipped with an aesthetic and spacious anti-draft weighing chamber made of glass featuring door. All elements of the chamber are made of glass or metal. With this, the influence of electrostatic field on the measurement result is minimized
  • Dedicated Software Specially designed RMCS computer software enables comprehensive realisation of calibration procedures in laboratory. The system manages the whole calibration process, starting from the moment the order is placed, through procedure performance, to the moment of issuing the calibration certificate.
