Product Description:

Thermal conductivity is an important parameter used to measure the thermal conductivity and insulation performance of heat-resistant materials, and the performance of heat-resistant insulation materials is determined by the material's thermal conductivity. The thermal conductivity of a material depends on many factors such as its composition, porosity, water absorption, moisture content, internal structure, and the environment and temperature during heat conduction. The intelligent flat panel thermal conductivity tester integrates water bath constant temperature equipment, and all measurements and controls are controlled by computers. The experimental program is written in Visual Basic 6.0, with an intuitive interface and easy operation. The data section is in Excel format, which is easy to operate and process. The test data curve can be saved and printed in real time, and the test records can be fully stored. Utilizing a computer interface to achieve fully automatic control of the instrument, data acquisition and processing, as well as calculation, display, and printing of thermal conductivity, the measurement time is short, the speed is fast, the data is accurate, the degree of automation is high, and the noise is low.
