Colorimeter based on color sensor

Abstract

In this paper colorimeter based on color sensor is considered. The developed colorimeter experimental utilization is shown on example of detection Cu2+, Co2+ ions and Neutral Red indicator. Realized measurement optical system in the colorimeter supports operation with different types of sorbents, as possibility is shown an operation with silica, polyurethane foam and the indicator paper. Dynamic range of device at 12 bit per channel and well stability of characteristic are enough to work with fine reliability that is no more 0.7% for analyzed test systems.
