Heat Flow Meter for Thermal Insulation Materials
The Heat Flow Meter for Thermal Insulation Materials is a precision instrument designed to measure the thermal resistance and thermal conductivity (k-value) of insulation products, building materials, packaging, and components. This user-friendly device provides reliable and repeatable measurements, enabling the quantification of heat transfer properties and overall thermal performance. Beyond characterizing the thermal behavior of materials, it helps define their energy efficiency, supporting material selection and quality control processes.
Application
Measuring thermal conductivity and resistance of insulation materials (rigid and flexible), building materials, and packaging.
Evaluation of thermal performance of components in construction and industrial applications.
Assessment of energy efficiency for materials used in insulation, thermal management, and packaging systems.
Applicable for quality control, R&D testing, and material certification.
