DRH-Ⅱ coefficient of thermal conductivity tester (the hot plate method)



DRH-Ⅱ Thermal conductivity meterDescription:

This instrument based on stable thermal conductive principle, one-way when sample, the two sides are in different stable temperature measurement, the heat transfer area through effective heat flow and surface temperature difference between the two, and thickness calculation coefficient of thermal conductivity. Meet the materials detection department of materials coefficient of thermal conductivity of high precision testing requirements. Instrument reference standard GB/T3399 "plastic coefficient of thermal conductivity test methods, the hot plate law, GB/T3139-2005 (fiber reinforced plastic coefficient of thermal conductivity test method) (FRP coefficient of thermal conductivity test method), GB / 10294-2008 (adiabatic material steady-state thermal resistance and related properties determination of hot plate protection method), etc. The main test plastic, glass, fiber, foam, heat preservation material, etc. Widely used in large and medium-sized college, scientific research units, quality inspection department and the material analysis detection manufacturer.
