ABSTRACT:
An improved temperature-compensated ion measurement method and apparatus for use therein. The method comprises placing a probe in a solution whose ion level (for example, pH) is to be measured and measuring the A.C. resistance of the probe in a manner that does not adversely affect the simultaneous measurement of the probe's D.C. potential, and then driving from these two measurements the ion level of the solution corrected for its temperature.
