Heat Flow Meter Thermal Conductivity Tester DW5720B

Heat Flow Meter Thermal Conductivity Tester DW5720B

DW5720B Heat Flow Meter Thermal Conductivity Tester is based on the steady-state method,  All testing functions automatically; Motor control of the plate movement; Measurement set up and run very fast; Sample sandwiched between two heat flux sensor test, fixed or adjustable temperature gradient.

In a few minutes after stability of temperature and temperature gradient, using the embedded controller or external computer measured the thermal conductivity (K), thermal conductance (C) and thermal resistance (R) of the sample.

Automatic upper plate move and sample thickness measurement, simplifies the test preparation. All test parameters and the correction data can be stored in the computer. It is mainly used to test the thermal conductivity, thermal resistance of building material, insulation materials, glass, fiber, foam and so on. Testing materials include fiber board, loosing filler glass fiber, ceramic fiber, foam plastic (XPS/EPS/PUR, etc.), inter-layer composite plate, vacuum plate, cement(concrete) products, glass rock wool, filler materials, gypsum board and so on. This coefficient of heat conductivity measurements conform to ISO 8301, JIS b 1412, DIN EN 12667, ASTM C518.

Here are the features of the machines:

• Fully insulated test chamber to avoid external influences
• Compensation for test piece’s thickness and the average temperature.
• External cooling with tap water or recirculation cooler for different temperature ranges.
• Equipped with an integrated Single Board Computer touch screen system.
• Interface: USB or RS232 connect to the additional PC installed with the thermal conductivity coefficient testing software.
