Product Description
The sensing element is a wire-wound electroplating thermopile, and the sensing surface is a black layer with high absorptivity. Utilize the thermal effect of radiation, absorb solar radiation to produce temperature difference, and output the measured value. It also has a temperature compensation function, which can accurately measure solar radiation.
