Heat Flow Meter Thermal Conductivity (Thermal Conductivity) Testing Service

Thermal conductivity is a critical property of materials that quantifies their ability to conduct heat. It is a measure of how effectively heat is transferred through a material when there is a temperature gradient. This property is denoted by the symbol 'k' and is expressed in watts per meter-Kelvin (W/m·K). Heat Flow Meter (HFM) thermal conductivity testing is a method used to determine the thermal conductivity of solids and loose materials, providing essential data for applications in various industries, including construction, aerospace, and energy systems.

Principles of Specific Heat Capacity Testing

From a scientific perspective, the HFM method involves placing an insulative sample between two plates held at a constant temperature difference. The heat flux through the sample is monitored until the system reaches a steady state. At this point, the heat flux, temperature difference, and sample thickness are used to calculate the thermal conductivity of the material. This method is based on the principle of Fourier's law of heat conduction, which states that the rate of heat transfer through a material is proportional to the negative gradient in the temperature and the area at right angles to that gradient.

Advantages of Specific Heat Capacity Testing

Our Services

At CD BioSciences, we specialize in providing comprehensive thermal conductivity testing services tailored to the needs of environment-friendly materials. Our service is designed to support the development and optimization of materials that have a reduced environmental impact while maintaining high performance standards.

Sample Preparation

The sample is cut or prepared to fit the dimensions of the test apparatus, ensuring a tight fit between the sample and the parallel plates.

Apparatus Setup

The sample is placed between the two parallel plates, and the temperature difference across the sample is maintained at a constant level.

Heat Flux Measurement

As heat flows through the sample, the heat flux is continuously monitored using a heat flux sensor until a steady-state condition is reached.

Data Acquisition and Analysis

The measured heat flux, temperature difference, and sample thickness are used to calculate the thermal conductivity of the sample material using the formula mentioned earlier.

Calibration and Validation

The HFM apparatus is calibrated using reference materials with known thermal conductivity values to ensure the accuracy of the measurements.
