Description

Effective and Excellent Measurement

The APP 4Y.KO series stands for a class-leading manual mass comparator. These weighing instruments allow to compare 100 g - 50 kg weights of class E1 and lower.

Excellent Measurement Repeatability

The APP 4Y.KO is comprised of two parts. One featuring an electromagnetic module, the other a precise mechanical measuring system. Weighing accuracy is assured thanks to a semi-automatic system of adjustment carried out using an external adjustment weight.

Design and Functionality

Weighing pan with a mechanical system for weights positioning facilitates precise loading of mass standards and eliminates eccentricity. This solution additionally allows for dissemination of reference mass to few weights.

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.
