The PHFS-09e, designed by FluxTeq, is the first low-cost large area heat flux sensor on the market. It is particularly useful for monitoring the performance of thermal insulation and direct in-situ measurement of insulation thermal resistance R-values. The sensor has minimal thickness and excellent sensitivity perfect for measurements on building thermal insulation.
