Abstract:
1. A method for monitoring content of a coating solution for coating components, the method comprising: supplying a tank with the coating solution comprising a concentration of a solvent and a concentration of a coating material; testing the concentration of the coating material using a titration process, wherein the titration process comprises controllably contacting a volume of the coating solution with a reagent solution to form a mixture, using a color processing device to generate input color data based on the color of the mixture, and detecting an end-point of the titration process based on the input color data, wherein the input color data is RGB data and the end-point of the titration process is detected by comparing the input color data with threshold color data, wherein the threshold color data comprises an RGB triplet; and supplying one or both of the solvent and the coating material to the tank based on an amount of coating solution contacted with the reagent solution when an input color data signaling the end-point of the titration process is generated by the color processing device, wherein the threshold color data comprises a range of RGB triplets determined by at least one previously performed titration reaction.
