HFP01SC self-calibrating heat flux sensor™ is a heat flux sensor for use in the soil. It offers the best available accuracy and quality assurance of the measurement. The on-line self-test verifies the stable performance and good thermal contact of sensors that are buried and cannot be visually inspected and taken to the laboratory for recalibration. The self-test also includes selfcalibration which compensates for measurement errors caused by the thermal conductivity of the surrounding soil (which varies with soil moisture content), for sensor non-stability and for temperature dependence. HFP01SC...

The result is a much improved accuracy & quality assurance of the measurement relative to measurements with conventional sensors such as model HFP01. Soil heat flux sensors are preferably left in the soil for as long as possible, so that the soil properties become representative of the local conditions. Using selftesting, the user no longer needs to take sensors to the laboratory to verify their stable performance. A typical measurement location is equipped with 2 or more sensors for good spatial averaging. Unique features and benefits – low thermal resistance – large guard area (required by...
