This series of thermal conductivity meters adopt the non-steady state method, which has the characteristics of fast measurement speed, wide application range, and the ability to successfully avoid the influence of natural convection during the experiment. It is a popular test method at present.

The DRE-2A thermal conductivity tester uses the transient double hot wire method to measure the thermal conductivity of liquids. It has the characteristics of fast measurement speed, less sample volume, high precision, high resolution, and high reproducibility. Automatic measurement is controlled by computer. It is widely used in the measurement of thermal conductivity of working fluids in the fields of petroleum, chemical, biological, pharmaceutical, energy, power engineering, etc.

The main technical parameters: Measuring range: 0.001~5.0 W/(m·K), 2. Temperature range: standard test: room temperature, (the thermal conductivity of the test sample needs to be equipped with a temperature controller at different temperatures, and the cost is extra, such as -20--120°C), 3. Measurement accuracy: <±3.0%, Sample dosage:<80ml, Measuring time: 10 seconds, Pressure environment: optional vacuum or pressure system (the cost is extra); Reference standard: ASTM D2717-95, 8. Sample shape: liquid; gaseous. 9. Power supply: voltage 220V; frequency 50Hz; power <500W, 10. Communication interface: USB interface. Instrument configuration: including 1 DRE-2A test host, 1 test probe, 2 glass test tubes, 1 test software, 1 communication interface and data cable, and 1 Lenovo desktop computer.
