The thermal conductivity of materials is an important parameter index for studying the thermo physical properties of materials. This series of instruments adopts the principle of the heat-protecting plate method, can be used to test the plastics, glass, fiber, concrete, building insulation materials, foam boards, powdery and other materials.
The DRH-ZD series is equipped with automatic pressurization and automatic thickness measurement functions to detect the thermal conductivity and thermal resistance under different pressure conditions. It is very suitable for compressible materials, with below features:Specifications
| Thermal conductivity range | 0.0010~3.0000w/m·k, show four decimal places |
| Test accuracy | ≤±3%;repeatability: ≤±1% |
| Hot surface temperature range | Room temperature~95ºC, resolution 0.01ºC |
| Cold surface temperature range | 0~60ºC, resolution 0.01ºC, controlled by constant temperature water tank (standard specification). Note: Low temperature detection optional: -20ºC~60ºC, -30ºC~60ºC, -40ºC~60ºC, etc. |
| Power supply | 220VAC/50HZ;≤2KW |
| Calorimetric power supply | Voltage 0-30V, resolution 0.0001V; current 0-3A, resolution 0.0001A |
| Test mode | Connect with computer for automatic test, data processing, and generate test report to realize data printout. |
| Sample size |
DRH-3-200×200×(5-20)(mm) ; DRH-300, DRH-ZD-300: 300×300×(10-50)(mm) ; DRH-400, DRH-ZD-400: 400×400×(10-80)(mm) ; DRH-600, DRH-ZD-600: 600×600×(10-100)(mm) ; |
