Ph精密试纸

pH precision test paper

Abstract

The utility model provides a pH precision test paper, which belongs to the technical field of test paper and comprises a bottom player and a reagent layer uniformly coated on the surface of the bottomlayer. The indicator in the reagent layer can be at least one of bromothymol blue, thymol blue, bromocresol blue and bromocresol green. The diverse reagent layer uniformly coated on the surface of the bottom layer of the pH precision test plate expands the scope of application of the pH test paper. Compared with the prior single-sheet test paper, the reagent layer directly arranged on the surfaceimproves the test sensitivity.
本实用新型涉及检测试纸技术领域,旨在提供一种PH精密试纸。该试纸包括纸制的基层,基层的表面还均匀涂布着一层试剂层,试剂层中的指示剂可以是溴百里香酚蓝、百里香酚蓝、溴甲酚蓝、溴甲酚绿中的至少一种。本实用新型的PH精密试纸,在纸制的基层表面均匀涂布着一层更多样化的试剂层,扩展了PH试纸的检测适用范围;而且相比之前的单片试纸,表面直接的试剂层可以使检测灵敏度做到更细。
