質(zhì)量比較儀可用于標(biāo)準(zhǔn)質(zhì)量的傳遞工作，從而并確保對(duì)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(dá)0.1ug，具有*的重復(fù)性。這兩個(gè)特性實(shí)現(xiàn)了一個(gè)已知參考砝碼和一個(gè)未知測(cè)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(guó)家標(biāo)準(zhǔn)質(zhì)量實(shí)驗(yàn)室、法定計(jì)量服務(wù)機(jī)構(gòu)，室內(nèi)校準(zhǔn)實(shí)驗(yàn)室，砝碼和檢測(cè)機(jī)構(gòu)。他們需要至高分辨率的測(cè)量。 

The newest line of Radwag Mass Comparators enable adjusting mass standards and weights according to the OIML recommendations (R-111) from 1 mg to 200 g for F2 class and lower.

The comparators are used both for ensuring traceability of mass measurements, and verification of weights in accordance with legal metrology. RADWAG Mass Comparators have gained recognition among Accredited Calibration Laboratories, in many countries.

Mass comparators series XA/3Y/KB comprise two components. One of them holds the electronic module, and the other precise mechanical measuring system.
Comparators feature an aesthetic, large weighing chamber with glass draft shield and automatic door opening system. Comparator is equipped with user friendly menu.
