Acid base indicator system

Abstract

This invention provides an acid-base indication system, comprising a substrate, a reagent set, an image capturing device, and a processor. The reagent set includes a standard reagent and a titrant, wherein a portion of the titrant reacts with the standard reagent to obtain a first reaction solution, and another portion of the titrant reacts with an unknown solution to obtain a second reaction solution. The image capturing device is disposed adjacent to the substrate and is used to capture target image data of the first reaction solution. The processor is signal-connected to the image capturing device and analyzes the target image data to output image color data, which corresponds to the reference acid-base value of the standard reagent. Therefore, by comparing the color of the unknown solution after reacting with the titrant with the image color data of this invention's acid-base indication system, the acid-base value of the unknown solution can be effectively detected.

Claims

1. An acid-base indicator system, comprising: a substrate having a accommodating space; a reagent set disposed in the accommodating space, the reagent set comprising: a standard reagent disposed in the accommodating space; and a titrant disposed in the accommodating space, wherein a portion of the titrant reacts with the standard reagent to obtain a first reaction solution, and another portion of the titrant reacts with an unknown solution to obtain a second reaction solution; an image capturing device adjacent to the substrate, and the image capturing device being used to capture target image data of the first reaction solution; and a processor signal-connected to the image capturing device, and the processor being used to analyze the target image data and output image color data, wherein the image color data corresponds to a reference acid-base value of the standard reagent; wherein... The color system of the second reaction solution is compared with the color data of the image to obtain the acid-base value of the unknown solution.
