欧洲Radwag（瑞德威）全自动质量比较器/质量比较仪：

质量比较仪可用于标准质量的传递工作，从而并确保对原器的可追溯性。 

欧洲Radwag(瑞德威)质量比较器天平的精度可高达0.1ug，具有*的重复性。这两个特性实现了一个已知参考砝码和一个未知测试样之间的比较称量。即使它们之间存在极小的质量差异。 

比较器天平的主要用户是：国家标准质量实验室、法定计量服务机构，室内校准实验室，砝码和检测机构。他们需要至高分辨率的测量。

Automatic mass comparators 全自动质量比较仪 AKM-4

Application 应用范围:

Automatic mass comparators series AKM-4/X are intended to automatic determination of mass deviations in weights with operator’s activity limited to the minimum. The comparators enable determining deviations of three tested weights in a signle cycle. AKM-4/X are designed to compare weights from 100 g to 2 kg. The instruments are commonly applicable in mass measuring laboratories, and particularly in certification units for weights classes E, F and M.

Design and functionality 设计和功能:

The supervising part of a 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 from level of mass indicating digital display which is plugged to mass comparator’s contoller. The supervising elements are not integrated with mass comparator’s mechanical parts, thus enabling separation of instrument’s weighing chamber from ambient conditions influence.
