Product Description
DRH300A Heat flow meter thermal conductivity tester
It is mainly used to test the thermal conductivity of insulation materials, glass, fiber, foam and so on. Testing materials include fiber board, loosing filler glass fiber, rockwool, foam plastic(XPS/EPS/PUR, etc.), inter-layer composite plate, vacuum plate, rubber products, cement(concrete) products, powder materials, filler materials, gypsum board and so on. DRH300 coefficient of thermal conductivity measurements conform to ASTM C 518, ISO 8301, JIS b 1412, DIN EN 12939, DIN EN 13163 with DIN EN 12667 and relevant international standards. It is in full compliance with the national thermal conductivity measurement standard with its stable and accurate temperature control technology, computer interface, software's real-time monitoring and control, data processing and saving connecting. With these advantages, it is applied widely in materials properties detection organization, scientific research institution, quality detection department of factory, institutions of higher education teaching and research.
Main features:
1. It has fuzzy guarded plate that is hot plate temperature tracking and precision control technology
2. Self-calibration function of the thermal conductivity and heating power
3. Compensation for test piece's thickness and the average temperature
4. WINDOWS automatic thermal analysis measuring software system, data analysis and reporting output function.
