DRH-V Automatic Thermal Conductivity Tester (Guarded Hot Plate) is used to measure the steady-state heat transfer through flat slab specimens by using the guarded hot plate method and calculate its heat conductivity of plastic, rubber, glass, fiber plate, polystyrene board, extruded sheet, foamed concrete, hollow glass, wood board and various thermal insulation materials. The slab specimen is placed between two flat parallel isothermal hot plates. Measure the heat flux through the effective area on the specimen, the temperature difference of two surfaces of the specimen and the thickness of the specimen to calculate the thermal conductivity.
