PHF-03 Prede Heat Flux Sensor

Key features

  • High sensitivity
  • Low internal resistance
  • Individual sensitivity values
  • Robust

The PHF-03 can measure the amount of transient heat per unit area of the surface, and read out the voltage output in mV.

Every single PHF-03 is individually calibrated with its own sensitivity, so that they are suitable to be used with data loggers.

The PHF-03 is low cost and easy to install (only two wires). The PHF-03 is also watertight, so that the sensor can be used for rooftop gardening with a water sprinkler.
