Abstract:
1. A computerized method for measuring water having high purity, comprising: collecting temperature measurements and resistivity measurements over a prescribed time interval from a temperature sensor and a resistivity sensor exposed to a water source; determining, by a computing assembly, at least one of a midpoint for temperature (T determining, by the computing assembly, a collected R/T slope from the collected temperature measurements and the collected resistivity measurements, in which the collected R/T slope is indicative of the change in resistivity versus change in temperature as measured over the prescribed time interval; comparing, by the computing assembly, the collected R/T slope to a standardized R/T slope at a temperature value corresponding to a midpoint temperature of the temperature measurements over the prescribed time interval; and providing, by the computing assembly, a compensated measurement for resistivity or conductivity of the water source based on the comparing.
