一种溶液表面张力测试仪的设计和开发

Micro-manometer Design for Surface Tension of Solution

对通常使用的最大起泡法测定液体表面张力的微压计进行改进,选用合适的具有高精度的传感器,同时采用VB设计上位机程序使其可将数据实时地传到上位机中。实验证明:该测试仪容易操作、可准确读取数据,并将数据保存在Excel中,方便处理。

The commonly-used micro-manometer for testing the maximum bubble liquid’ s surface tension was improved, in which, the proper sensor with high accuracy was employed and the real-time data were transmit-ted to PC with the help of VB-based PC program.Experimental results show that the improved micro-manome-ter can be operated easily in accurately reading and saving the data in the Excel for processing.
