Applications and Technical Parameters of Thermal Conductivity Testers

The thermal conductivity tester is primarily used to measure the thermal conductivity of materials such as plastics, glass, fibers, and foams. The instrument follows standards including GB/T3392-82 "Test Methods for Thermal Conductivity of Plastics, Guarded Hot Plate Method"; GB/T3139-2005 (Test Methods for Thermal Conductivity of Fiber Reinforced Plastics) and (Test Methods for Thermal Conductivity of Fiberglass); GB/T10801.1 and GB/T10801.2 (for thermal insulation polystyrene foam), among others. It also references GB/T10295-1988 "Determination of Steady-State Thermal Resistance and Related Properties of Thermal Insulation Materials - Heat Flow Meter Method"; ISO/DIS8301 "Thermal Insulation - Steady-State Thermal Resistance and Related Properties - Heat Flow Meter Apparatus"; ASTMC518-2004; and EN12667. The tester is applied in material performance testing institutions, scientific research organizations, factory quality inspection departments, and higher education institutions for teaching and research. Main technical parameters of the thermal conductivity tester: 1. Thermal conductivity range: 0.015 to 2 W/m·K. 2. Maximum temperature: Hot plate: 80°C with a heated constant temperature water tank; Cold plate: can be equipped with a refrigerated constant temperature water tank to cool below room temperature. DRX-I-PC model: Hot plate: less than 300°C with heater control, cold plate: can be equipped with a refrigerated constant temperature water tank to cool below room temperature, and the minimum temperature can reach -20°C. The DRX-I-PC model can be equipped with dual specimen and single specimen testing devices. 3. The instrument achieves digital temperature measurement with an accuracy better than 0.2 grade. 4. Measurement result accuracy: ±3%. 5. Measured heating power: 35W ±1%. 6. Sample size requirements: 200×200×(5-20) mm or 300×300×(5-50) mm available for selection. 7. Depending on user testing requirements for materials, it can be equipped with thermal resistance testing methods and heat flow meters and testing instruments.
