QSD-2 type pendulum experimental apparatusDetailed product description：

The measurement of the pendulum period of the QSD-2 pendulum experimental instrument is controlled by a photoelectric gate and recorded by an intelligent instrument, which has the advantages of accurate data collection and small errors. This product has a novel design, stable and reliable performance, advanced detection equipment, and is an ideal physics experimental teaching equipment for colleges and universities.

This product consists of two parts: QSD-2 single pendulum experimental apparatus and single pendulum experimental platform:

Single pendulum experimental platform: The main body is composed of 10cm organic glass plates, etc., marked by height and angle; The suspended part of the ball is investigated using a knife edge wire wheel, and the single pendulum period is counted using a photoelectric gate to greatly reduce errors. Single pendulum experimental instrument: using a new type of microcontroller to store and process the input signal of the photoelectric sensor, it can automatically record and store multiple sets of experimental result data, and accurately calculate the average value of multiple sets of experimental data. In addition, this instrument can also measure the rotation period of rigid bodies, the rotational speed of rotating bodies, and can be used as a universal timer.
