CONTAINER FOR GRADUATING FLUID, OXYGEN ELECTRODE OF APPARATUS FOR MEASURING PARAMETER OF FLUID SAMPLE, AND METHOD AND APPARATUS FOR MEASURING PARAMETER OF FLUID SAMPLE

摘要

PROBLEM TO BE SOLVED: To measure the parameters of a fluid sample by keeping the closed state through the use of a container in an apparatus thereby sustaining a constant concentra tion of saturated gas for a standardization fluid during storage, installation and use of a container. ;SOLUTION: Samples of measuring fluid, standardization fluid and functional fluid are fed to a measuring chamber for a specified time and the physicochemical characteristics are measured for the measuring fluid and standardization fluid using a measuring electrode. When a fluid is standardized for the measuring electrode in the measuring chamber, oxygen from the atmosphere is introduced in addition to a standard aqua solution saturated with gas. The solution being accompanied sequentially and alternatively with the measuring sample or functional sample according to the measuring period is then branched between at least two measuring channels provided in the measuring chamber of an analyzer 1 provided with an electrode for measuring the equilibrium of acid and base. The measurements are checked for each channel by means of a general purpose electronic system and a PC computer 4.;COPYRIGHT: (C)1996,JPO
