Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figure 1-3, a special tray for pH test paper detection, including a bottom plate 1, a side wall 2 is provided on the outer side of the top of the bottom plate 1, and the top of the bottom plate 1 is located inside the side wall 2 with multiple sets of pH test paper 7. The shape is a square with a side length of one centimeter. A bottom groove 3 is opened at the middle position of the top of the chassis 1. The bottom groove 3 runs through the top of the chassis 1 and extends to the bottom end of the chassis 1 and is connected with a collecting groove 4. The bottom end of the collecting groove 4 is provided with There is a swivel 5, the inside of the swivel 5 is connected with a filter screen 6, the top of the swivel 5 is provided with an internal thread 9, and the bottom end of the chassis 1 is located outside the collection tank 4 with a beaker 8.
