In detail
Rapid thermal conductivity meter (thermal conductivity measuring instrument)
Rapid thermal conductivity instrument using transient plane heat source method, this instrument is based on TPS transient plane heat source technology, using Hot Disk as the probe thermal conductivity measuring instrument.
The advantages of the Hot Disk method are:
1. Direct measurement of heat propagation can save a lot of time;
2. It will not be affected by the contact thermal resistance as the static method;
3. No special sample preparation is required, and only a relatively flat sample surface is required for solid materials. It has the advantages of fast measurement speed, wide application range and successfully avoiding the influence of natural convection in the experiment process, so it is a popular test method at present. Equipment reference standard:
ISO 22007-2 2008. It is equipped with a special round sample cylinder for rock and soil measurement.

The thermal conductivity of rock and soil (stone) can be measured by the transient plane heat source method, which is an accurate and rapid test method. Transient planar heat source method (TPS) is a test technology based on the principle of unsteady thermal conductivity. It is suitable for the thermal conductivity test of materials from insulation to high thermal conductivity.
This method has the following characteristics:
1.Direct measurement of heat propagation: saves a lot of time and is not affected by contact thermal resistance.
2. No special sample preparation: for solid materials, only a relatively flat sample surface can be tested.
3. Wide range of application: different types of materials can be used in different test schemes and calculation mathematical models, with fast measurement speed, can successfully avoid the impact of natural convection in the experimental process and other advantages.
4. Equipment reference standards:
ISO22007-2:2008, GB/T32064-2015, etc., to ensure the standardization and accuracy of the test method.
