Problems solved by technology
[0002] When preparing chemical solutions in a chemical laboratory, a hand-held electric stirrer is generally used to stir the mixed solution. The ordinary hand-held electric stirrer is just a small motor with a propeller-type stirring on the extended shaft. However, in the process of preparing chemical solutions, the differences in pH values of various solutions and the temperature changes caused by chemical reactions will be involved. In the actual operation process, if the timely mixing state cannot be grasped and controlled, it will be Inaccurate solution preparation occurs, and various relevant data during the experiment cannot be obtained at the same time

Embodiment Construction
[0009] Shown in the embodiment of the drawings: a thermometer 2 is connected to one side of the electric stirrer 1, and a pH value tester 3 is connected to the other side. A handle 4 is arranged above the electric stirrer 1 .
[0010] When in use, hold the handle 4 above, place the stirring head below the electric stirrer 1 in the solution, the thermometer 2 and the pH value tester 3 on both sides are placed in the solution at the same time because they are connected as one, and the electric stirrer is started After 1, the thermometer and the pH value tester will simultaneously respond to timely data, and when idle, just hang it on a fixed object through the handle 4 on the top.

The invention provides a hand-held electric stirrer used in chemical experiments. A thermometer is connected to one side of the electric stirrer, a pH value tester is connected to the other side, and a handle is arranged above the electric stirrer. When using an electric stirrer for laboratory chemical solution mixing and preparation, the temperature and pH value of the solution can be grasped and tested while stirring the solution, which is beneficial to make the prepared solution more accurate and obtain more accurate experimental data .
Description
technical field [0001] The invention relates to a hand-held electric stirrer, in particular to a hand-held electric stirrer used in chemical experiments. Background technique [0002] When preparing chemical solutions in a chemical laboratory, a hand-held electric stirrer is generally used to stir the mixed solution. The ordinary hand-held electric stirrer is just a small motor with a propeller-type stirring on the extended shaft. However, in the process of preparing chemical solutions, the differences in pH values of various solutions and the temperature changes caused by chemical reactions will be involved. In the actual operation process, if the timely mixing state cannot be grasped and controlled, it will be The phenomenon of inaccurate solution preparation occurs, and various relevant data during the experiment cannot be obtained at the same time. Contents of the invention [0003] The purpose of the present invention is to solve the technical deficiencies of the a...
