DRH-300 Thermal Conductivity Equipment

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 “Testmethode voor thermische geleidbaarheid van kunststof, 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) enzovoort. Test vooral plastic, glas, vezel, foam, insulation materials, enz. Op grote schaal gebruikt in hogescholen en universiteiten, wetenschappelijke onderzoekseenheden, quality inspection departments and production plant material analysis and testing.
