[0025] Specifically, after the detection box 5 is rotated, the limit block 19 will be rotated together, so that the limit block 19 moves in the annular groove 18, and starts a certain limit effect on the detection box 5 to prevent the detection box 5 from deflecting during the rotation process.

[0026] Furthermore, a sealing plate 16 is provided on the surface of the stirring shaft 11 , the bottom of the sealing plate 16 contacts the bottom of the fixing groove 15 , a first sealing groove 20 is opened at the bottom of the sealing plate 16 , and a sealing ring 17 is fixedly connected to the top of the first sealing groove 20 .

[0031] Then, in order to better mix the water reducer in the detection box 5, the stirring motor 6 can be rotated by the control device 10. The rotation of the stirring motor 6 will rotate the stirring shaft 11, and the rotation of the stirring shaft 11 will rotate the stirring blades, thereby better stirring the liquid inside the detection box 5 and making it more evenly mixed.

[0032] As for the operation of the stirring motor 6 and the rotating motor 7, both of them can be started, or only one can be started.

[0033] After the water reducer in the detection box 5 is stirred and mixed evenly, the electric telescopic rod 8 is started. The electric telescopic rod 8 is extended and retracted to extend the concentration sensor 14 to different positions in the detection box 5, so that the concentration of the water reducer can be better measured.
