1．Measure the heat conductivity coefficient of poor conductor by steady-state method and compare to the theoretical value
2．Measure the heat conductivity coefficient of aluminum alloy bar to analyze the defect of steady-state method.)
a) Separate the temperature controller and testing jig to guarantee safe and convenience.
b) Controlling temperature and testing temperature are used by two different meters for no effects.
c) Adopting RTD sensor to measure the temperature of heating plates and cooling plates. The LED can display the temperature directly toimprove the accuracy. (For different requirements, we can change the RTD to thermocouple to improve automatic freezing temperature compensation circuit.
d) User can set the maximum temperature by PIN to avoid high temperature harming sensors and instruments.
e) Equipped with poor conductor, metal and etc. Adopting comparison method to measure heat conductivity coefficient of different materials.
