APP 30.4Y.KO Mass Comparator in Mass Comparators

Overview

The newest line of Radwag Mass Comparators enables adjusting mass standards and weights according to the OIML recommendations (R-111) from 5 kg to 20kg 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. RADWAG Mass Comparators have gained recognition among Accredited Calibration Laboratories in many countries.

Mass comparator APP 4Y.KO series comprises two components. One of them holds the electronic module, and the other precise mechanical measuring system.
High measuring accuracy is guaranteed by semi-automatic adjustment system with external mass standard. The weighing pan made of aluminium is covered with cork layer and features centering holders for the weights. The APP 4Y.KO series features an intuitive menu supporting a user in instrument operation.

CAUTION:

For correct mass standards comparison process using comparator, it is required to use an anti-vibration granite table and an anti-draft chamber.

Anti-draft chamber comes standard with the comparator. Anti-vibration table and its parameters are to be found here: Anti-vibration tables for APP balances and comparators
