General
PHF-02 and PHF-03 measures the amount of transient heat per unit area of the surface, and read out the voltage output in mV.
Every single PHF-02 and PHF-03 were individually calibrated with it's own sensitivity, so that they are very suitable to be used with data logger.* *Sensitivity of PHF-02 is Approx. 40 to 60W/m2/mV, therefore, if the resolution of 1W/m2 is required, datalogger with 10 micro V (=0.01mV) would be required.
