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.

Replaceable Heat Flow Module: Tool-free replacement of the calibrated heat flux sensor module.
Comprehensive Temperature Monitoring: Multiple thermocouples ensure sample temperature gradient is at steady-state during testing.
Precision Thickness Measurement: Proprietary universal design allows automated thickness measurement for rigid materials or user-defined thickness/pressure for compressible samples. Optical encoders provide ±0.025 mm accuracy.
Temperature Control: Heat exchanger with thermocouples enables precise heating and cooling; lateral heat loss minimized using guarded furnace; software allows precise temperature programming.
Clamping Control: Automatic clamping for rigid samples; software-controlled height/pressure (up to 379 kPa / 55 psi) for soft materials, with automatic stop once desired parameters are reached.
Steady-State Measurement: Ensures accurate thermal resistance and conductivity by maintaining stable temperature gradients through the sample.
