The HFP01SC self- calibrating heat flux sensor™ is a sensor designed for high precision measurement of soil heat flux. It is a mixture of a heat flux sensor and a film warmer. The basic role is to measure the heat flux through the surrounding soil. The HFP01SC output is a voltage indicate that is relative high temperature flux through the sensor. The film warmer that is mounted on top could be actuated to perform an alignment, ensuing in another calibration factor that makes up for the slips made in light of the current situation of that minute. Likewise failures because of temperature reliance and inability of the sensor are abolished. The result is a much enhanced precision & quality certification of the measurement.
