The HFP01 provides soil heat flux measurements—typically for energy balance or Bowen ratio flux systems. It outputs a voltage signal that is proportional to the heat flux of the surrounding medium. At least, two sensors are required for each site to provide spatial averaging. Sites with heterogeneous media may require additional sensors.

Features

Typically used in Bowen ratio and energy balance systems
Intended for applications that do not require self calibration
Voltage output proportional to local heat flux
Minimum of two soil heat flux measurements are recommended for a homogeneous site
