The Power of Heat Flow Meter Thermal Conductivity Technology

2025.02.24

Energy conservation and emission reduction have become top global priorities. A key strategy to achieving these goals is the research and promotion of materials with enhanced insulation properties. Thermal conductivity is central to understanding a material’s thermal performance and plays a crucial role in the development of energy-efficient insulation solutions.

Zeal Instruments provides advanced, high-precision Heat Flow Meter Thermal Conductivity equipment, designed to accurately measure the thermal conductivity of insulation materials within a range of 0.001 W/(m·K) to 2 W/(m·K).

The Science Behind the Magic

How It Works

The Heat Flow Meter (HFM) is a precise tool for measuring thermal conductivity. It works automatically to simplify testing and improve accuracy. A sample, up to 300 × 300mm in size, is placed between two heat flow sensors. The thickness can range from a few millimeters to 100mm, making it suitable for different materials.

Once the sample is in place, a temperature gradient is applied. The temperature difference between the top and bottom can be fixed or adjusted. After a few minutes of stabilization, the system measures thermal conductivity and resistance. Automatic controls ensure quick and accurate results with minimal human input.

Why It Matters

The HFM is designed for ease of use. It has motor-controlled plates that move automatically during testing. It also measures sample thickness automatically, reducing preparation time and human error. Users can operate the system with the built-in controller or connect an external computer for advanced control.

The HFM is best for measuring low to medium thermal conductivity materials. These include polymers, ceramics, glass, rubber, composites, and some metals. It is widely used in materials science, construction, and environmental testing. Heat moves from warm to cool areas. By measuring this heat flow, the HFM calculates a material’s thermal conductivity. This data is essential for energy efficiency assessments, making the HFM a valuable tool in research and industry.

Why It Matters Now

Addressing Global Energy Demands

Materials with low thermal conductivity are particularly valuable in energy-saving applications, such as insulation for buildings, electrical components, and industrial equipment.
