1、Short hot wire method (short hot wire method high-temperature melt thermal conductivity instrument)

Testing principle:

Based on the principle of energy conservation, the thermal diffusion coefficient and thermal conductivity of the liquid are solved by solving steady-state thermal conductivity problems. The thermal conductivity of the liquid medium is calculated by measuring the temperature rise response of the sensor.
