Introduction
This comprehensive experimental apparatus consists of a control unit and independent functional modules. The control unit integrates measurement and display units for parameters such as temperature, pressure, voltage, and current with high-precision long time timing unit, PID control and manual control unit, multiple sets of DC power supply unit, and four-way sensor interface unit. Each functional module is specifically designed for a set of particular experiments (at present, there is only one module available and more modules will be added when they become available).
Using the control unit and module # 1, the following experiments can be performed:
(1) PID applications
(2) Heat conductive coefficient measurement of a poor conductor
(3) Heat conductive coefficient measurement of air
(4) Heat conductive coefficient measurement of a metal
(5) Specific heat capacity measurement of a metal
(6) Linear expansion coefficient measurement of a metal
The instruction manual contains experimental configurations, principles, step-by-step instructions, and examples of experiment results. Please click Experiment Contents and Results to find more information about this apparatus.
