Large Area Heat Flux Sensor – PHFS-90e

The PHFS-09e  from FluxTeq is a thin, large surface area sensor that is perfect for measuring heat or R-values on walls and building envelopes. It has high sensitivity, robust thanks to its metal foil encapsulation, is inexpensive, and is NIST traceable.

Feature Highlights

  • Thermal monitoring of buildings and insulation
  • In-situ R-value measurements
  • R&D
  • Thermal energy efficiency
  • Heat transfer education

Features and Specifications

Can be used for various applications such as measuring energy efficiency of buildings, R-value measurements, R&D, and use in teaching heat transfer concepts.
