一、调配工作液体及冲洗仪器有些检定员在拿到斜管式微压计(以下简称“微压计”)后,发现盒状容器内盛有工作液体,调整好零位后马上检定,结果示值超差。我们知道,斜管式微压计的工作液体为密度0.81kg/cm3的乙醇,乙醇是一种在常温、常压下易挥发的无色透明液体,经常使用会使得盒状容器内的乙醇密度发生变化。在检定微压计时,原有的工作液体密度无法测量,也就不能保证其密度就是0.81kg/cm3。密度没有达到要求,检定结果的
First, the deployment of the working fluid and rinse instruments Some examiners get oblique tube micro-pressure meter (hereinafter referred to as Micro-pressure meter ), found that box-shaped container filled with working fluid, adjust the zero immediately after the test, Results show that the value of ultra poor. We know that the working fluid of the inclined tube micro-pressure gauge is ethanol with a density of 0.81 kg / cm3. The ethanol is a colorless and transparent liquid which is volatile at normal temperature and pressure. Frequently, the density of ethanol in the box-shaped container occurs Variety. In the test micro-pressure meter, the original working fluid density can not be measured, it can not guarantee its density is 0.81kg / cm3. Density did not meet the requirements, test results
