HFP03 is an ultra sensitive sensor for measurement of small heat fluxes in the soil as well as through walls and building envelopes. The total thermal resistance is kept small by using a ceramics-plastic composite body. See also model HFP01: putting several HFP01 sensors electrically in series is an alternative for using HFP03.
