Light intensity LI-210R

Measures light intensity (µMol/m2/S) between 400-700nm. Typical applications include PPFD (Photosynthetic Photon Flux Density) measurement over plant canopies in outdoor environments, greenhouses, and growth chambers. Connects to our brain box for data logging, calculate your DLI, get real time alerts and automate your artificial lights or shatters.
