DRH-300导热仪

The instrument is based on the principle of unidirectional stable heat conduction. When the upper and lower sides of the sample are at different stable temperatures, the heat flow through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample are measured to calculate the thermal conductivity. It meets the high precision test requirements of material testing research department for thermal conductivity of materials. Instrument reference standards: GB/T3399 “塑料导热系数测试方法, heat plate method”, GB/T3139-2005 (fiber reinforced plastic thermal conductivity test method) (glass fiber reinforced plastic thermal conductivity test method), GB/10294-2008 (thermal insulation material steady-state thermal resistance and related characteristics of the determination of protective hot plate method) and so on. 主要测试塑料, 玻璃, 纤维, 泡沫, insulation materials, ETC. 广泛应用于高等院校, 科研单位, quality inspection departments and production plant material analysis and testing.
