Thermtest - Model GHFM-01 - Guarded Heat Flow Meter
From Thermtest Laboratory Thermal Conductivity Measurement Instruments
The GHFM-01 Guarded Heat Flow Meter is designed to test the thermal resistance and thermal conductivity of both homogeneous and heterogeneous materials. Best For Metals, Polymers, Composites, and Pastes.
The Guarded Heat Flow Meter (GHFM-01) follows ASTM E1530-19 for testing thermal resistance and thermal conductivity of solids, such as metals, polymers, composites and paste from -20 °C to 310 °C. The Thermtest proprietary testing stack, replaces the traditional pneumatic movement with advanced motor control, which allows automated control of testing sample thickness, force or pressure applied.
