The anti-falling
PH meter comprises a PH device body, the right side of the PH device body is fixedly connected with a supporting rod, the front side of the supporting rod is fixedly connected with a supporting plate, the surface of the supporting plate is provided with a containing groove, the inner side of the containing groove is movably connected with a testing
pipe, the upper side of the supporting rod is fixedly connected with a limiting plate, and the limiting plate is fixedly connected with the right side of the supporting rod. A baffle is movably connected to the inner side of the limiting plate, and a stabilizing plate is fixedly connected to the right side of the PH device body. By arranging the baffle, after the
test tube is placed on the inner side of the supporting plate, the end opening of the
test tube can be shielded through the baffle, the phenomenon that other solution gas makes contact with the
test tube, and consequently the test is inaccurate is avoided, by arranging the lifting stud, the protective shell can ascend and descend, and therefore the outer side of the test tube can be protected conveniently; the test tube is prevented from being collided, the use stability of the device is improved, and the problems that the
PH meter is in contact with other solution gas and the PH test tube is broken are solved.
