Abstract
A method and system for the determination of the pH of a fluid by measuring the pH of the fluid and thereafter correcting the pH based upon the determination of measured and/or adjusted values of at least one other parameter, such as PO.sub.2 and PCO.sub.2, which relate to the fluid.

A method for determining the pH of a fluid using a metal monocrystalline electrode comprising the steps of:
- a. measuring the pH of the fluid by exposing the metal monocrystalline electrode to contact with the fluid while connecting the electrode to a power supply source and a means for analyzing signals received from the electrode to obtain a measured pH value of the fluid;
- b. measuring at least one further parameter relating to the fluid to determine a measured value for said at least one further parameter;
- and
- c. determining a corrected pH value of the fluid by adjusting the measured pH value of the fluid based upon the measured value of said at least one further parameter.
A system for determining the pH of a fluid by initially measuring the pH value of the fluid and thereafter determining a corrected pH value by adjusting the measured pH value based upon the measurement of at least one further parameter of the fluid, the system comprising:
- at least one metallic monocrystalline electrode adapted to be contacted with the fluid, a first electrical circuit connecting the at least one electrode between a source of power and means for analyzing an output from at least one electrode to measure the pH value of the fluid, and means for determining the value of the at least one other parameter of the fluid to obtain a parameter value of the at least one other parameter and means for obtaining the corrected pH value of the fluid by adjusting the measured pH value of the fluid based upon the parameter value of the at least one parameter.
