This instrument adopts the international popular heat flowmeter detection thermal conductivity method, with a computer to achieve automatic detection, is optimized on the basis of the original HZ-7039K, to meet the test requirements of the thermal conductivity of various common materials.
Based on the test principle of steady-state plate method, adding stable heat surface temperature to the heat surface. The heat is transferred to the cold surface through the sample to measure the transmitted heat flow, and then the thermal conductivity and heat resistance can be calculated according to the thickness and heat transfer area of the sample.
This Thermal Conductivity Tester flat plate heat flowmeter method is simple, quick, and highly reproducible.It is very suitable for the research and development of material heat transfer.Can be used in plastic, rubber, graphite, thermal insulation materials and other testing, widely used in universities, scientific research institutes, quality inspection, factories and mines.
Reference standard for this instrument: ASTM C518-04 Test method for determining steady state heat flux and heat transfer characteristics by heat flowmeter; GB10295-2008 determination of steady state heat resistance and related characteristics of thermal insulation materials (heat flowmeter).
