1.Description:
This instrument adopts the internationally popular method of using
thermal flow meters to measure thermal conductivity and thermal
resistance. It is equipped with a computer to achieve fully
automatic testing and generate experimental reports. It is
redesigned based on the DRPL-I type flat plate thermal flow meter
for thermal conductivity testing instrument produced by our
company, and is capable of meeting the testing requirements of
400×400×(5-80) insulation bricks.
This instrument is based on the steady-state plate method testing
principle. A stable temperature is added to the hot surface, and
the heat passes through the sample to the cold surface. The
transferred heat flow is measured. Then, the thermal conductivity
and thermal resistance can be calculated based on the thickness of
the sample and the heat transfer area. This testing method is
simple, fast, and has good repeatability. It is very suitable for
research and development in material heat transfer. It can be used
for testing of rocks and soils, foams, cement, insulation
materials, etc., and is widely applied in universities, research
institutes, quality inspection, factories and mines.
