:roll: dose anyone have any info schematic diagrams ect for a electrical conductivity meter used to measure the electrical conductance of a soultion also any info on PH meters
thx

measuring electrical conductance ... I would use a resitance meter for that

I'm not sure what system commercial pH meters use, but I do know that you have to be careful not to apply too much voltage across your electrodes, otherwise you can cause unwanted chemical reactions to occur...

Take a look at the 3rd circuit, "Circuit provides constant current for ISFETs/MEMFETs"
