ABSTRACT
Digital Colorimeter is an instrument used to measure the absorbance of wave-length of light at a particular frequency (color) by a sample available. The instrument available so far requires lots of manual operations. The novel Colorimeter meter developed in this paper is efficiently used to overcome that problem. With the help of microcontroller based system it can calculate the absorbance value of solution of different concentration more effectively. A touch screen display has been used for providing an interactive system. This paper provides designing of an interactive, portable and cost effective Digital Colorimeter that is capable of measuring absorbance values more effectively with the provision of storage also.
