Mesin Konduktiviti Thermal DRH-III

Gambaran keseluruhan:

The thermal conductivity of materials is an important parameter to study the thermal physical properties of materials. The instrument adopts the principle of heat shield plate method, which meets the high precision test requirement of material testing research department for thermal conductivity of materials. Instrument reference standards: GB/T3399 “Plastic thermal conductivity test method, 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. Mainly test plastic, kaca, serat, foam, powder and so on. Widely used in colleges and universities, scientific research units, quality inspection and production enterprises and other departments.

The instrument is improved and optimized on the basis of the original DRH-Ⅱ, with higher degree of automation and more stable performance.
