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.
Accessories
Contact paste for top and bottom surfaces.
Optional software module for custom temperature programming.
Standard calibration samples with known thermal resistance and conductivity.
Refrigeration circulator for low-temperature testing.
Test Procedures
Sample Preparation: Ensure sample diameter is 50–50.8 mm and top/bottom surfaces are flat and parallel. Apply a thin layer of contact paste (~1 min).
Load Sample: Place the sample into the test stack. For rigid materials, the upper stack applies default system pressure. For soft materials, define the desired pressure or thickness. Parameters can be controlled within the test plan (~1 min).
Measurement: Set single or unlimited temperature steps (up to 300°C). Internal red backlight indicates test in progress (~40–60 min).
Export Results: Temperatures of upper and lower test plates are monitored to ensure stability. Thermal resistance and calculated conductivity are displayed in tabular form and can be exported to Excel. Internal blue backlight indicates test completion and safe handling (~1 min).
Maintenance Information
Regularly clean thermocouple and heat flux sensor surfaces to avoid debris interference.
Periodically check calibration using reference samples with known thermal properties.
Inspect mechanical components of motorized stack and encoders to maintain accuracy.
Store in a dry, temperature-stable environment when not in use.
