歐洲Radwag（瑞德威）全自動質(zhì)量比較器/質(zhì)量比較儀：

質(zhì)量比較儀可用于標準質(zhì)量的傳遞工作，從而并確保對原器的可追溯性。 

歐洲Radwag(瑞德威)質(zhì)量比較器天平的精度可高達0.1ug，具有*的重復性。這兩個特性實現(xiàn)了一個已知參考砝碼和一個未知測試樣之間的比較稱量。即使它們之間存在極小的質(zhì)量差異。 

比較器天平的主要用戶是：國家標準質(zhì)量實驗室、法定計量服務機構，室內(nèi)校準實驗室，砝碼和檢測機構。他們需要至高分辨率的測量。

Automatic mass comparators 全自動質(zhì)量比較儀 AKM-4

Application 應用范圍:

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 設計和功能:

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.
