Heat flux sensor HFP01SC
The HFP01SC self-calibrating heat flux sensor is a sensor intended
for high accuracy measurement of soil heat flux. It also offers
improved quality assurance of the measurement. The on-line calibration
(the Van den Bos-Hoeksema method) automatically corrects for various
common errors, in particular those due to the non-perfect matching
of the thermal conductivity of sensor and soil, and due to variations
of the thermal conductivity of the soil caused by varying moisture
content. |
