摘要
通过缩小测试点间隔,浸没方式采用全浸和局浸两种,并改变局浸深度,本文对7支量程0℃~50℃、最小分度值0.1℃工作用玻璃液体温度计进行示值误差测试,并对检定时出现的一些常见问题进行探讨,包括恒温槽使用注意事项、检定过程中注意事项、感温液柱中断修复。
By narrowing the interval between the test points,using two kinds of full immersion and partial immersion in the immersion mode,and changing the local immersion depth,the following conclusions are drawn on the indication error test of 7 glass liquid thermometers with a range of 0°C~50°C and a minimum graduation value of 0.1°C.Some common problems during the verification are discussed,including the precautions for the use of the thermostatic bath,the precautions during the verification process,and the repair when the temperature sensing liquid column is interrupted.
