CHF Series

The CHF Series cooled heat flux sensors developed by Nextherm Sensing are designed for the continuous and instantaneous measurement of high heat fluxes, from a few kW/m² up to several MW/m².
Derived from the GHF radial thermal gradient technology, these sensors integrate an optimized liquid cooling system for stable and long-term operation, even under very high heat flux conditions.
Available in radiative, convective or total heat flux versions, they are suitable for a wide range of laboratory tests and demanding industrial environments.
