DRE-2 B coefficient of thermal conductivity tester (transient probe method)
DRE-2 B coefficient of thermal conductivity test instrument used transient probe method, suitable for measuring the high inviscid fluid, colloidal particles, powder, materials coefficient of thermal conductivity, the temperature coefficient (thermal diffusion coefficient) and specific heat. This instrument will hotline method and probe method, ensure the accuracy of measurement in and greatly improve the operation of the portability, users only will probe is inserted into the test samples, through the simple software click operation that could get tested samples of the coefficient of thermal conductivity, especially suitable for field measurement.
Main features:
1. Convenient operation and test speed, measurement accuracy
2. Especially for field measurement
3. No special shape of a sample request
4. The test automation software, easy to operate
5. According to the sample temperature with the system, can test samples under different temperature coefficient of thermal conductivity.
The main technical indexes:
1. Measurement range: 0.01 ~ 5.0 W / (m • K)
2. The range of compression: normal pressure
3. Temperature range: room temperature, (testing samples under different temperature coefficient of thermal conductivity temperature controller, costs to match another plan, such as-40 to 120 ℃)
4. Fine degrees: < plus or minus 3.0%
5. Sample shape: loose material
6. Sample usage: length less than 10 cm in diameter not, not less than 3 cm (amount and probe size for relevant)
7. Measuring time: 5 minutes
