Multiple standard liquid bottles are placed in a recess within the upper cover of the box, and a desulfurized gypsum dosage comparison chart is placed below the standard liquid bottles. A water-soil mixing bottle, constant volume cup, and quantitative soil sampler are placed in a recess within the lower cover of the box. The upper and lower covers of the box are fastened together with a buckle, and the box is equipped with a handle. Soil is collected from the field, water is added to prepare a soil solution, and after centrifugal oscillation, the solution is compared with the standard solution.
