Electrode Holder (pH Detector) for High Temperature and High Pressur

概要

論文の詳細を見る
This paper describes a trial manufacture of pH detector (flow cell and immersion cell) in which pressure compensation is made utilizing the pressure in the measuring system to continuously measure pH value of solution under high temperature and high pressure. It was proved that the operation of pH detector manufactured in this experiment goes stable up to 120°C, 5kg/cm<SUP>2</SUP> as a upper limit of experimental apparatus. Also given in this paper is the effect of natural electrode potential generated on the electrode holder by a creep of inner solution (potassium chloride solution) of reference electrode.
