I have the following circuit to measure the conductivity of water ( aim is to measure dissolved minerals concentration), I have taken this circuit from this research paper. I have checked the solutions for which I want to measure conductivity & the range is roughly from 800k - 1.5M ohms.
My aim is to increase the range of output from the wheatstone bridge, which right now is almost flat & non-linear. The graph shows sweep output of RC resistance from 500K - 1.5M with the at IP1 & P1 respectively.
How can I do that? I have observed this same behaviour in the actual circuit that I had built.
