Middleton Solar - Model SK01-D2 and SK01-DP -Photodiode Pyranometer
FromMiddleton Solar
The SK01-D2 is a simple pyranometer for monitoring total solar global radiation on a plane surface. The SK01-DP2 version incorporates a special interference reflector to limit its sensitivity to the Photosynthetically Active Radiation region of the solar spectrum (400-700nm).
