    Development of Palmtop Digital Electrical Conductivity Meter

    • The basic development principle of palmtop digital electrical conductivity meter was introduced. Through numerical computation, a method that using phase analytical method to correct lift-off effect in the impedance plane was put forward. Based on the principle, the meter system was designed by using high performance microprocessor AT91RM9200. And the design method of hardware and software were explained.
