DRPL-I thermal conductivity tester (flat heat flow meter)

I. overview

and amp;This instrument uses the international popular heat flow meter to measure the thermal conductivity and thermal resistance. It is equipped with a computer to realize the full-automatic detection and generate the experimental report. The instrument uses a stable hot surface temperature on one side of the sample. The heat is transferred to the cold surface (room temperature) through the sample, and the heat flow is measured to calculate the thermal conductivity and thermal resistance

This test method is simple, fast and has good repeatability. It is very suitable for research and development of heat transfer of metal materials such as profiles. It can also be used for testing of rock, soil, plastic, rubber, glass, graphite, thermal insulation materials, etc. It is widely used in colleges and universities, scientific research institutes, quality inspection, factories and mines.

Reference standard of this instrument: GB / t10295-2008 (determination of steady-state thermal resistance and related characteristics of thermal insulation materials by heat flow meter method) and ASTM C518-04 test method for steady-state heat flux and heat transfer characteristics by heat flow meter method
