DRE-2B Soil Thermal Conductivity Tester

DRE-2B Thermal conductivity tester adopts transient probe method, which is suitable for measuring thermal conductivity of high viscosity fluid, colloidal, particle, powder and other materials. The instrument combines the hot wire method with the probe method, which greatly improves the portability of operation while ensuring the measurement accuracy. Users only need to insert the detector into the tested sample, and the thermal conductivity of the tested sample can be obtained by simple software click operation. It is especially suitable for the test of soft materials and different shapes of the finished product and field detection.

Main features:

1. Convenient operation, fast test speed, accurate measurement,

2. Especially suitable for field measurement,

3. No special shape requirements for the sample,

4. Automated test software, easy to operate,

5. With the sample temperature according to the device, the thermal conductivity of the sample can be tested at different temperatures.

Main technical indicators:

1. Measuring range: 0.0100 ~ 5.0W /(m·K)

2. Pressure range: normal pressure for conventional testing, (high pressure device can be selected according to user experimental requirements, do 0-10mpa, 0-15mpa and other high pressure testing, the cost is calculated separately);

3. Temperature range: the conventional test is room temperature, (according to the user’s experimental requirements, the temperature control system can be selected at different temperatures, such as -20–100℃, 0–100℃, room temperature –120℃, etc., the cost is calculated separately),

4. Accuracy: <± 3.0%,

5. Sample shape: loose material such as liquid, colloidal and loose solid.

6. Sample dosage: length is not less than 10cm, diameter is not less than 3cm (dosage is related to the size of the probe)

7. Measurement time: 5 minutes,

8, Instrument reference standard: ASTM D5334-2014 Test method for the determination of thermal conductivity of soil and soft rock by hot needle probe method.
