FHF05 is the product range to start looking if you consider measuring heat flux. Models are available in five different dimensions and sensitivities. All FHF05’s are flexible, have an integrated temperature sensor and have thermal spreaders to reduce thermal conductivity dependence. Rated temperature range is from –70 to +120 °C. FHF05 measures heat flux from conduction, radiation and convection.
