HPL220P Response spectrum range of PPFD is 400nm-700nm，It is applicable to the PPFD measurement of plant canopy in outdoor environment, greenhouse and growing room, as well as the PPFD measurement of reflection or under canopy (transmission) in the same environment.
To ensure accuracy, each sensor is carefully calibrated under controlled conditions. The sensor integrates silicon photodiodes and customized filters. Typical applications include PPFD / par measurement of plant canopy in outdoor environment, greenhouse and growing room. The measurement results can be viewed on OLED display.
