The invention discloses a pH test paper packing box facilitating quick and accurate color comparison. The pH test paper packing box comprises a cylindrical box body and a matched box cover and is mainly characterized in that the upper end of the box cover is provided with a round groove, the inner diameter of the round groove is equal to the inner diameter of the cylindrical box body and is 13-18 mm, 14 equal pH value standard color comparison lumps are arranged on the inner side of the circumference at the upper end of the wall thickness part of the round groove, each pH value standard color comparison lump is of a sector structure, and the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14 marked on the outer side of the circumference at the upper end of the wall thickness part of the round groove represent pH values corresponding to the pH value standard color comparison lumps respectively. The pH test paper packing box facilitates packing and carrying of pH test paper of a round structure, can simplify the operation mode and improve the accuracy of a test result when used for testing the acid-base property of a reagent, and is particularly suitable for field operation.
