摘要
本文介绍了一种改进的、原理简单的溶液密度测量装置——磁浮密度计,讨论了影响精密度和准确度的因素。该装置简单,操作简便,速度快,精密度、灵敏度分别为±2×10^(-6)、0.3×10^(-6),其准确度通过测定19.89℃时国际标准海水P105的密度得到了验证,我们的测定结果和别人的极好地一致。
A simple, modified magnetic float densimeter that can be used to determine the density of solution is described and the factors that influ- ence its precision and accuracy are discussed in detail. The densimeter have advantages of simple apparatus, fast determining.Its precision and sensi- tivity is 2×10^(-6), 0.3×10^(-6),respectively .Its accuracy has been verified by measured the density of the International Standard Seawater P105 in 19.89℃.Our results are excellent agreement with the others works.
