This instrument utilizes the steady-state method to test thermal conductivity of non-metallic plate materials, making it ideal for quality control, research and development, and material certification applications.

Fully compliant with international standards including ISO 8302, ASTM C177, and national standard GB/T10294-2008 for protected hot plate method thermal conductivity measurement.

The instrument operates on the principle of one-way stable thermal conduction, placing two samples between the hot plate and side cold plates. When stable thermal conditions are achieved, thermal conductivity is calculated by measuring electrical power, temperature differential across sample surfaces, and sample thickness. The optimized design ensures heat flows exclusively from hot to cold surfaces without lateral loss, providing exceptional measurement accuracy.
