Product catalog summary
Introduction
The HFP03 is an ultra-sensitive heat flux sensor designed for measuring small heat fluxes in soil and through building materials. It features a ceramics-plastic composite body and a thermopile sensor, which measures temperature differences without requiring power. It is suitable for flux levels less than 1 W/m2, particularly in geothermal applications.

Calibration and Standards
The HFP03 is calibrated according to international standards, following ASTM C1130 practices. It can measure building envelope thermal resistance and transmittance per ISO 9869, ASTM C1046, and ASTM 1155 standards.

Uncertainty Evaluation
Measurement uncertainty depends on sensor properties, calibration, and temperature sensitivity. Users should conduct their own uncertainty evaluations.

Suggested Use and Options
Ideal for extremely small heat fluxes and geothermal applications. Options include longer cables and using multiple HFP01 sensors for cost-effective, high-sensitivity measurements.

HFP03 Ultra-sensitive heat flux plate heat flux sensor 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.

HFP03 measures heat flux through the object in which it is incorporated or on which it is mounted, in W/m2. HFP03 is specifically suitable for measurement of small flux levels, in the order of less than 1 W/m2, for instance in geothermal applications. The sensor in HFP03 is a thermopile. This thermopile measures the temperature difference across the ceramics-plastic composite body of HFP03. A thermopile is a passive sensor; it does not require power. Using HFP03 is easy. It can be connected directly to commonly used data logging systems. The heat flux in W/m2 is calculated by dividing the HFP03...
