Product Description
Xiangke DRJ-II Metal High-Temperature Thermal Conductivity Tester Metal Thermal Conductivity Meter
This instrument adopts the method of direct sample energization and longitudinal heat flow. It is suitable for measuring the thermal conductivity of metals without phase change in the temperature range of 80°～900℃, and the test is automatically completed by a computer. It meets the testing requirements of metal material thermal conductivity for material testing and research departments. Instrument reference standard: GB/T3651-2008 "Measurement method for high-temperature thermal conductivity of metals".
