Abstract

Kits for an LED-base colorimeter and a potentiometer for ion-selective electrodes, dedicated to high school or undergraduate student experiments, have been developed. These kits are intended not only to provide experience chemical analysis, but also for manufacturing analytical instruments for themselves. A micro-controller was used to simplify the electronic circuit, to reduce costs, and to provide practical analytical performance to those kits. Both kits can be built within 2 hours and at expenses of less than 10 thousand yen. After the time and easiness for assembly and the analytical performance were evaluated with prototypes, print circuit boards for them were manufactured. These kits were used in lectures for high school students, high school teachers and undergraduate students. Almost all students were able to complete the kit within a given time, and could apply it to analytical experiments.
