Product Description


DRH-300 Double Specimen Guarded Hot Plate Thermal Conductivity Tester


    The design and manufacture of the instrument is completely according to GB/T 10294-2008 / ISO 8302: 1991 heat insulating material steady state thermal resistance and related characteristic- guard hot plate method. The whole measurement and control adopt computer control to reduce personal error and improve test precision.

The instrument is mainly used in testing plastic,fibre,foam,thermal insulation material,refractory material etc. plate material, add with a sample frame can test powder and creamy materials. Widely applied to heat-resisting and heat preservation material manufacture enterprises,quality inspection department,institutions of higher learning and research institution etc.     


Main features:
1. With real-time measurement and reading devices, it can automatically measure test piece


2. With test piece pressure online real time detection, display and control functions


3. It has fuzzy guarded plate that is hot plate temperature tracking and precision control technology


4. Self-calibration function of the thermal conductivity and heating power


5. Compensation for test piece’s thickness and the average temperature
