Abstract
Multi-channel pH sensor based on the color change from the organic dye was examined. Six pH indicators were selected for wide pH measurement range. Absorption spectra of the visible light were evaluated to six pH indicators. Moreover, pH valuation of the absorption spectra was evaluated for the optical pH sensor application.
