Compact Ion Meter Using a Flat Electrode: Applications
Author: Katsuhiko Tomita; Hiromi Okawa; Junji Kojima
– This paper introduces and discusses applications of the Cardy series pH meter, ion meters and conductivity meter; all of which have been developed with a new line of compact testers for chemical analysis. These products feature a newly developed sheet-type electrode, which allows measurements to be made using a very small amount of sample. The discussion centers on possible applications that advantage of this feature including: (1) measuring acid rain, (2) analyzing the fluid secretions in living bodies, and (3) determining the acidity of paper. Also discussed is the Twin pH meter, which permits measurements to be carried out either by dipping the electrode in a sample (like conventional desk-top pH meters) or by placing a very small amount of sample on the pH sensor.
