Instrument overview:
1. The methods of measuring thermal conductivity can be roughly divided into two categories: steady-state method and dynamic method. This tester uses the steady-state method to measure the thermal conductivity of different materials. Its design idea is clear and simple, and the experimental method is typical and practical. Measuring the thermal conductivity of a substance is an important part of thermal experiments.
2. This tester consists of a heater, a digital display thermometer, a digital display timer, etc. (adopting an integrated design).
