摘　　要：本文介绍了一种测量范围为１ｍｍＨｇ—２０ｍｍＨｇ，测量精度为０．１ｍｍＨｇ的低真空测量装置及其使用条件和方法。有效地代替了以水银为媒质的旋转式麦氏真空计。A low vacuum measuring device,with its measuring range lmmHg -20mmHg and precision 0.1mmHg,its conditions and method for application are presented in this paper.It very well replaces rotary McLeod gauge which uses mercury as its medium.
