DRX-II Thermal Conductivity Tester (hot wire method)

The hot wire method is a dynamic measurement method (non steady state method). The principle is to measure the temperature rise of a linear heat source buried along the length direction of the sample for a certain period of time. Measure the temperature of the hot wire over time by welding a thermocouple at the midpoint. The temperature change of this line is a function of the thermal conductivity of the tested material.

Standard:

GB/5990-2006 "Test method for thermal conductivity of shaped insulating refractory products (hot wire method)";

GB/T10297-2015 "Determination of thermal conductivity of non-metallic solid materials (hot wire method)"
