The Development of a New Type of Conductivity Meter
The new type of conductivity meter uses the square wave excitation. We selected the scope of sampling band unaffected by polarization and capacitance from the half-period of square wave. We obtained the voltage signals during the period of the selection, and removed the signals during other periods, thus achieved the more accurate conductivity values. The meter utilizes thermostat to control temperature and temperature compensation to reduce the impact of temperature. The methods above greatly improve the measurement accuracy of the conductivity meter.
