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.
