DRP-II Wood Thermal Conductivity Apparatus
สรุป
The methods of measuring thermal conductivity can be divided into two categories: steady state method and dynamic method. The tester uses the steady-state method to measure the thermal conductivity of different materials. The design idea is clear, simple, and the experimental method is typical and practical. Measuring the thermal conductivity of a substance is an important content in thermal experiments.
This tester is composed of heater, digital thermometer, digital timer, ฯลฯ. (integrated design)
