Heat Flow Meter HFM-25

The cost effective HFM-25 unit was designed to meet the growing need for steady-state testing of small samples of insulation for true thermal resistance and thermal conductivity. Plate contact is controlled manually with variable pressure applied using standard weights. Thickness is conveniently reported with included digital gauge. Ambient room temperature is automatically detected. One heat flux sensor is integrated into each plate and is used to monitor heat flux (Q/A), generated due to the difference in temperature (DeltaT) between the top and bottom plate at regular intervals until steady-state heat flux is observed. The composite heat flux is then used to measure thermal resistance (R) and calculate thermal conductivity (λ) according to Fourier's Law.
