DRE-2C Thermal Conductivity Tester (Transient Plane Heat Source Method)

The DRE-2C thermal conductivity tester adopts the transient planar heat source method, mainly measuring the thermal conductivity, thermal diffusion coefficient, and specific heat capacity of solids, powders, coatings, thin films, anisotropic materials, etc. This instrument is based on TPS transient planar heat source technology and uses Hot Disk as the probe for thermal conductivity measurement.

The advantages of the Hot Disk method are:

(1) Directly measuring heat propagation can save a lot of time;

(2) Will not be affected by contact thermal resistance like static method;

(3) No special sample preparation is required, only a relatively flat sample surface is required.

Main technical indicators:

1. Thermal conductivity measurement range: 0.0100-300W/mk, resolution: 0.0001 W/(m · K);

2. Measurement time: 1-600 seconds,

3. Accuracy: better than 5%,

4. Temperature range: Standard measurement: Room temperature (testing temperatures for various temperature ranges can be selected according to customer requirements, with additional costs such as -20 ℃ to 120 ℃),

5. Sample size: diameter ≥ 45mm, thickness ≥ 15mm (if a single layer is not enough, multiple layers can be stacked for testing), relatively flat sample surface, powder material can be directly inserted into the probe for testing;

6. Instrument reference standards: ISO 22007-2008 and GB/T32064-2015 transient planar heat source test method for thermal conductivity and thermal diffusion coefficient of building materials DZ/T0276.14-2015 Geological and Mineral Industry Standards of the People's Republic of China - Experimental Procedures for Physical and Mechanical Properties of Rocks Part 14: Thermal Conductivity Test of Rocks GB/T 11205-2009 "Determination of thermal conductivity of rubber (transient hot filament method)"

7. Easy to operate and fast to test, simply clamp the testing probe between two sample blocks, and obtain the thermal conductivity of the tested sample through simple software clicks.

8. Power supply: voltage 220V; Frequency 50Hz; Power<500W,

9. Communication interface: USB interface.

10. Probe diameter: 7.5mm or 15mm, two specifications are optional.

Configuration

1 DRE-2C testing host, 1 testing probe, 1 set of testing software, 1 set of communication interface and data cable, 1 desktop computer (configured according to the contract), and 1 sample fixture.
