Thermal conductivity refers to the amount of heat transferred per unit area of a material along the direction of heat flow at a unit temperature gradient over a unit time. The unit is watts per meter Kelvin [W/(m · K)].

Test scope: foamed plastics (heat insulation materials and plates with flat surface), polyurethane, phenolic aldehyde, urea formaldehyde, mineral wool (glass wool, rock wool, mineral wool), cement walls Glass reinforced composite panel CRC, cement polystyrene board, sandwich concrete, fiberglass composite panel, paper honeycomb board

Measurement certificate

Instrument features:

1. The surface temperature is accurate and uniform. In the design, a large area of whole piece copper plate is used as a temperature control measuring board to improve the consistency of the surface temperature of the tested sample.

2. Advanced control system. It can quickly and stably control the temperature.

3. Friendly human-machine interface. The temperature of the cold and hot plates, as well as the heat flow power, can be intuitively displayed on the large LCD screen.

4. Concise operation. Electric mobile clamp, adjustable clamping force LCD display, automatically closes the insulation door after the sample is installed in place

5. Intelligent data processing. A highly automated computer data communication and report processing system, with a flat thermal conductivity meter equipped with a computer communication interface for real-time display of temperature curves.

6. Automatically generate test reports and print them. The software has built-in experimental records, data processing, and report formats, and automatically generates experimental reports.
