本文介绍了一种新型质量比较器，旨在测量 2 毫克及以下的小重量，可读性为 10 纳克。质量比较器是使用新型线圈和执行器开发的。添加的保护环将线圈的平均吸附引起的质量变化降低了 84%。新型比较器的准确性在稳定性、A 型不确定度和重复性方面得到了验证。与现有最佳精度的设备相比，新颖设计的比较器的标准不确定度大约缩小了 70%。
This paper presents a novel mass comparator designed for the purpose of measuring small weights of 2 mg and lower, with readability of 10 ng. The mass comparator was developed using new types of coil and actuator. The added protective ring decreased the average sorption-induced mass variation for the coil by 84%. The accuracy of the novel comparator was verified in terms of stability, Type An uncertainty, and repeatability. Compared to the device of the best available accuracy, the standard uncertainties of the novel-design comparator were approximately 70% narrower.
