摘要

Abstract

Chemical experiments are a rigorous task. In order to make classroom teaching more interesting and convenient and to lower the cost of teaching tools

the author has developed a "four function integrated measuring instrument" that can measure temperature

pressure

conductivity and pH value. In order to verify the applicability of the measuring instrument

this article compares the self-developed "four functional integrated measuring instrument" with the basic situation of the "Vernier sensors" on the market and verifies the performance indicators of the measuring instrument by using the "four functional integrated measuring instrument" to complete conductivity measurement experiments and pH measurement experiments. The "four functional integrated measuring instrument" that meets the experimental requirements will be used to complete the acid-base neutralization reaction experiment in the chemistry class of junior high school and the learning effect of students will be evaluated. Finally

using the measuring instrument to further expand the experimental content of oxygen content measurement in the course and improve teaching effectiveness.
