| Abstract: | Aiming to the complex physical properties of liquid lead to the difficulty in measuring its resistivity, a new liquid-resistivity measuring device is designed in this paper. In order to collect the information of the object under test effectively, the container is designed skillfully. Graphite electrode is applied innovatively to realize the integration of the electrode and the container, which improves the measuring accuracy. The sensing technology is used to collect voltage and current signals and transmitted the data to the MCU. The value of resistivity is displayed on the LCD screen in real time after the operation of the MCU. With the advantages of quick and accurate measurement, it has certain practical value in teaching and research. |
