Liquid thermal conductivity tester Transient hot wire method thermal conductivity tester

The DRE-2A thermal conductivity tester adopts the transient hot wire method, with a single or double hot wire optional, mainly measuring the thermal conductivity of liquids. It has the characteristics of fast measurement speed, small sample size required, high accuracy, high resolution, and high reproducibility. Automatic measurement is controlled by a computer. Widely applicable for measuring the thermal conductivity of working fluids in fields such as petroleum, chemical, biological, pharmaceutical, energy, and power engineering.

Main technical parameters:

1. Measurement range: 0.0010~5.0 W/(m · K),

2. Temperature range: Standard test: Room temperature, (the thermal conductivity of the test sample at different temperatures requires a temperature controller, and the cost will be calculated separately, such as -40-120 ℃),

3. Measurement accuracy:<± 3.0%,

4. Sample dosage:<80ml,

5. Measurement time: 10 seconds,

6. Pressure environment: optional with vacuum or pressure system (cost to be calculated separately);

7. Reference standard: ASTM D2717-95 Test method for thermal conductivity of liquids,

8. Sample shape: liquid; Gaseous state.

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

10. Communication interface: USB interface.

Instrument configuration: including 1 DRE-2A testing host, 1 set of testing probes, 2 glass test tubes, 1 set of testing software, 1 set of communication interface and data cable, and 1 desktop computer (configured according to the contract).

If a constant temperature device and a pressure device are required, the cost will be charged separately.
