Automatic mass comparatorAK-4AK series is intended to automatic determination of weights mass deviations with operator’s activity limited to the minimum. The comparator enables determining deviations of three tested weights in a single cycle. . The instrument is commonly applicable in mass measuring laboratories, and particularly in certification units for weights classes E1 and M1. depending on the model

The supervising part of the mass comparator is a digital module which cooperates with a controller of instrument’s mechanical components. The digital module and the automatic loader are located in mass comparator’s weighing chamber. The instrument is operated by means of digital display which is plugged to mass comparator’s controller. The supervising elements are not integrated with mass comparator’s mechanical parts, thus enabling separation of instrument’s weighing chamber from ambient conditions influence.

• Effective and Excellent Measurement The AK-4 automatic mass comparator enables determining mass deviations of weights with the minimum possible operator participation. The comparator allows to compare weights of class E1 and lower of mass ranging between 10 g and 10 kg.
• Comparison of Mass Standard Sets There are two versions of the mass comparator: 4-position for 1 reference weight and 3 test weights, and 2-position for reference weight being a combination of mass value of 3 separate weights.
• Excellent Measurement Repeatability AK-4 automatic mass comparator, due to the elimination of the human factor, temperature changes and air drafts, guarantees excellent measurement repeatability when compared to manual mass comparator.
• Design and Functionality An element that controls mass comparator operation is a digital management module, which is placed inside comparator’s chamber along with an automatic mass standard feeder. Mass comparator is operated by means of indicator connected to the comparator controller. Control elements are not mechanically integrated with the construction thanks to what the influence of ambient conditions on mass comparator chamber is significantly reduced.
• 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.
