Thin-film heat flux sensor FHF06

high-temperaturemonitoring

Overview
The FHF06 is a high-temperature foil heat flux sensor designed for applications requiring reliable heat flux measurements at temperatures up to 250 °C. Its all-polyimide construction eliminates the need for adhesives, enabling continuous operation in demanding thermal environments. Like all FHF series sensors, the FHF06 is thin, flexible, and versatile, making it suitable for measuring heat transfer by conduction, convection, and radiation.

Key features
