DRE-III multi-function fast thermal conductivity tester ISO 22007

1.use

This instrument uses the transient plane heat source method, based on TPS transient plane heat source technology, with Hot Disk probe. The advantages of this instrument 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 needed, and only a relatively flat sample surface is needed for solid materials. Different test schemes and calculation mathematical models are used for different types of materials, which have the advantages of fast measurement speed, wide application range and successfully avoiding the influence of natural convection during the experiment. The actual test material range is wide, the thermal conductivity range is wide, the sample processing is simple, the test speed is fast advantages, is currently more popular test method.

Equipment reference standard: ISO 22007-2:2015, GB/T32064-2015.

Test materials: Metal, alloy, graphite, thermal conductivity silicone grease, silica gel, silicone rubber, ceramics, geotechnical, rock, polymer, paper, fabric, foam plastic, concrete, composite board, paper honeycomb board and other solid, powder, liquid, paste, coating, film, insulation materials, insulation materials, anisotropic materials such as thermal conductivity, thermal conductivity coefficient (thermal diffusivity) and specific heat capacity, heat storage coefficient and Thermal resistance.
