Configured for heat-transfer measurement, this low-cost, thin, flexible heat flux sensor measures ±150 kW/m² from -58 to 248°F (-50 to 120°C). It uses a differential-temperature thermopile that attaches easily to round surfaces, with ~0.6-second response and a Type-T surface thermocouple. It suits R&D, energy-efficiency, and wearable applications.
