Conductivity Sensor

[AlphaRugal79]

Hello All,

I want to measure the conductivity of the ground water. I have already selected the sensor which is of the type Gold plated interdigital structure on epoxide substrate. Now I need the circuit that would generate the alternating current and measure the voltage developed accross the electrodes. If you know of any schematics or any IC packages then please let me know....
