Heat Flux Sensor - PHFS-01

The PHFS-01 heat flux sensor is an inexpensive NIST traceable sensor for long-term use for monitoring heat transfer through walls, pipes, ducts, etc. Although it is extremely thin, it is very sensitive and reliable. It can be used in R&D for studying heat transfer components and for measuring the energy efficiency.
