Thermal conductivity refers to an important parameter of material thermal conductivity. At present, there are many methods to measure thermal conductivity, such as steady state method and unsteady state method. Compared with other methods, this measurement method has the advantages of fast measurement speed, high precision, simple sample preparation, etc. It can be applied to the measurement of thermal conductivity of various materials, and is widely used in universities, ceramics, metals and composite materials industries.

How to measure thermal conductivity and how to operate?

Thermal conductivity measurement operation method:

1. Sample preparation. According to the material properties, if it is a solid material, cut to the specified size to ensure that the surface is relatively smooth; If it is a liquid or powder material, place it in the corresponding container for fixed measurement.

2, select the probe. DZDR-S thermal conductivity tester has two probes, according to the nature of the material, to choose the probe type, if it is a low conductivity material to choose the No. 1 probe; High conductivity material selection Probe 2. The probe is fully in contact with the sample surface. For solid samples, the probe is placed between two solid samples and fixed with a fixture to avoid loosening the probe. If it is liquid, place the probe in a fixed position.

3. Set parameters. Depending on the material, set the measured time, resistance and power.

4. Connect software. Connect the instrument to the computer, open the analysis software, enter the adjusted parameters, click to start the experiment.

5. Calculate thermal conductivity. DZDR-S thermal conductivity tester can calculate the thermal conductivity within 5~160s, and the software can calculate the thermal conductivity directly.

The above is the measurement operation method using the transient heat source method in the non-transient method. In order to improve the accuracy and reliability of the measurement results, we must strictly follow the standard of sample preparation, size and corresponding parameters in the measurement operation process, and repeatable measurement can be carried out. DZDR-S thermal conductivity tester can also measure films, pastes, colloids, inorganic materials, etc., the operation is simple and fast.
