HZ-7039G Thermal Conductivity Tester Double Heat Protection Plate Method

The instrument is based on the principle of one-way stable thermal conductivity. When the upper and lower sides of the sample are at different stable temperatures, the heat flow of the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces are measured to calculate the thermal conductivity.It meets the requirements of the high-precision test of the material thermal conductivity of the material detection and research department.Instrument reference standard: GB / T3399 "Plastic Thermal conductivity Test Method, thermal protection plate method", GB / T3139-2005 (thermal conductivity test method of fiber reinforced plastic) (FRP thermal conductivity test method), GB / 10294-2008 (thermal insulation material steady state thermal resistance and related properties of protective thermal plate method), etc.Main test plastic, glass, fiber, foam, insulation materials, etc.It is widely used in colleges and universities, scientific research units, quality inspection departments and manufacturers of material analysis and testing.
