Description

An experimental instrument for teaching demonstration

technical field

The utility model belongs to the field of teaching equipment.

Background technique

When the current chemical experiment teaching equipment is used, especially when the reaction needs to measure PH, it needs to be repeatedly measured, which not only wastes time, but also wastes test paper and increases the cost. At the same time, the temperature must be repeatedly measured.

Contents of the invention

The purpose of this utility model is: for the above-mentioned existing problems, provide a kind of experimental instrument for teaching demonstration, comprising:

The bottle body, the upper end of the bottle body is open, wherein the bottle body can be designed according to needs, such as Erlenmeyer flasks and the like.

The pH sensor is located on the inner wall of the bottle and is used to detect the pH value of the solution in the bottle. The specific parameters of the pH sensor can be designed according to the needs, and the existing ones can basically meet the requirements. The sensor can simply collect Data, at this time, needs to be connected to a processor, and the processor is connected to the display. In a specific embodiment, it also has the function of processing data. At this time, the function can be realized by directly connecting the display. In a word, the PH of the present invention includes a processor.

The display is connected with the pH sensor and is arranged on the bottle body, and the display is a display capable of digital display.

As an improvement, the bottom of the bottle body is also provided with bumps to increase friction.

As an improvement, a temperature sensor is also provided in the bottle, and the temperature sensor is connected to a display.

As an improvement, a layer of rubber sheath is provided on the outer wall of the bottle body, and the rubber sheath is used for heat insulation.

In summary, due to the adoption of the above technical solution, the utility model has the beneficial effects that: the utility model can instantly display the pH value of the liquid during the experiment, which can be instantly fed back to the experimental steps, and is easy to operate.
