The Guarded Heat Flow Meter is a precision instrument designed to measure the thermal resistance and thermal conductivity of solids, including metals, polymers, composites, and pastes, over a temperature range of -20°C to 310°C. By replacing traditional pneumatic motion with advanced motorized control, the system achieves automatic adjustment of sample thickness, applied pressure, and force. This instrument provides highly accurate steady-state measurements, enabling precise evaluation of materials’ thermal performance and aiding in quality control, research, and energy efficiency assessment.
Application
Measurement of thermal conductivity and thermal resistance of metals, polymers, composites, and pastes.
Characterization of thermal performance for materials in aerospace, electronics, automotive, and industrial applications.
Determination of steady-state heat transfer for heterogeneous or non-uniform materials.
Applicable for quality control, material research, R&D, and certification testing.
Standards
ASTM E1530: Standard Test Method for Evaluating Thermal Resistance of Materials Using a Guarded Heat Flow Meter.
ASTM E1560-19: Standard Test Method for Thermal Conductivity Measurements with Guarded Heat Flow Meter.
