  VBR-100 Quantum PAR Meter 6000umol

  VBR-100 Quantum PAR Meter 6000umol   Test PAR | PPFD for any light spectrum accurately. Can show the PAR of red and blue light in light seperately. Blue light is efficiently absorbed by plant chlorophyll. Red light is conducive to the growth of flowers and the maturation of fruits. Calculate DLI if the PPFD is stable. Record PPFD data at different points methodically by grids and get the PAR Uniformity(Uo). Optimized Growth, ensures even light for balanced plant growth and higher yield.I ncreased Efficiency, identifies weak spots to adjust light placement, reducing energy use. Prevents Light Issues, Avoids damage from too much light and growth issues from too little. The datas can be downloaded. Simple and safe APP for test PAR. Quick bluetooth connection. Easy to carry the PAR meter.The PAR Meter can be fixed on the drone or toy car to test PPFD anywhere in the greenhouse. No need for the tester to move around.
