Guarded Heat Flow Meter GHFM-01

rightMORE INFORMATION

  • The GHFM-01 Guarded Heat Flow Meter is designed to test the thermal resistance and thermal conductivity of both homogeneous and heterogeneous materials such as metals, polymers, composites and pastes from -20 °C to 310 °C. The proprietary testing stack replaces the traditional pneumatic movement with advanced motor control allowing automated control of testing sample thickness, force or pressure applied. The sample is subjected to a steady-state through-thickness temperature gradient and the thermal conductivity is obtained by measuring the temperature difference across it and one additional reference temperature.

  • - Full computer control of GHFM-01; mean temperature, sample thickness, force or pressure applied.
    - Programmable mean temperatures from -20 °C to 300 °C.
    - Multiple high resolution (0.01 °C) thermocouples for accurate measurement of thermal resistance and thermal conductivity.
    - Thickness is measured to an accuracy of 0.0254 mm with use of a digital optical encoder.
    - Integrated force sensor with feedback loop for controlling stepper motor.
    - High performance stepper motor enables plate clamping to be automated or set to a user defined thickness – ideal for compressible materials.
    - Flux modules are easily changed, with no tools needed.
    - Follows international standard; ASTM E1530-19.
