A singlechip computer controlled conductivity meter based on conductance-frequency transformation
- 物理技术－会议论文 
A portable conductivity meter controlled by singlechip computer was designed. The instrument uses conductance - frequency transformation method to measure the conductivity of solution. The circuitry is simple and reliable. Another feature of the instrument is that the temperature compensation is realised by changing counting time of the timing counter. The theoretical based and the usage of temperature compensation are narrated.
