TC 3000L Series Hotline Liquid Thermal Conductivity Meter

Introduction:

 The TC 3000L series adopts the transient hot wire method to measure the thermal conductivity of liquids. The hot wire method is also the best method for measuring liquids in the field of international thermal conductivity research. It can be applied to all polarities and non-critical areas except for rare gases and non-critical areas. Polar fluid. In the Recommended Physical Fluid Properties for Liquids published by the International Union of Pure and Applied Chemistry (IUPAC), toluene and pure water are used as primary reference materials for liquid thermal conductivity measurements, and the primary thermal conductivity data for these substances are Obtained by the hot wire method, the measurement accuracy is 1% or better (less than 0.5%), so the transient hot wire method is also recommended as a primary measurement method for liquid thermal conductivity measurement (Primary Method). Since 2010, the National Institute of Standards and Technology (NIST) has released experimental data and fitting equations for thermal conductivity over a wide temperature and pressure range for over ten substances including Methanol, Ethanol, n-Heptane, n-Hexane, Benzene, and Toluene. One of the most important criteria for data screening is that the primary measurement method must be used for experimental measurements, and most of the primary data sources for these substances are also obtained using the hot line method.

Features:

1. Accurate measurement: The resolution is up to 0.0005W/(m ̇K), the accuracy can be within 0.5%, and the whole range is less than 3%, so it can ensure the need of scientific research.

2. Fast test: It takes only 2 to 3 minutes to connect the instrument, prepare the sample, click on the software, and finally obtain the data.

   Users don't have to stay next to the instrument. They only need to export the data after the test is finished, which can greatly save the user's test time and effort.

3. Small amount of sample: No special treatment is required for the test sample. Only need to ensure that the sample volume is not less than 25 ml, the experiment can be conducted, and the test cost can be significantly reduced.

4. Easy to operate: The user can accurately operate without any professional knowledge and obtain experimental data.

5. Widely applicable: The hot wire method thermal conductivity meter is not only suitable for scientific research laboratories and enterprise quality control departments, but also applies to the on-line inspection of products to ensure the control of product quality at any time.
