Test PPFD accurately accoding to McCree Curve. Record DLI every second.. PPFD serves as a measurement of PAR, representing the number of PAR photons received per m per second.. Has a telescopic wand to fix the senosr for PPFD test.. Can also test the CCT, temperature, humidity, and VPD..

FH-100 can test the PPFD accurately. The main spectra of LED CMH, HPS and SUNLIGHT are different,plants have different perception abilities for these light sources, and the meter have special design for this.. When testing PPFD in a closed tent, you can close the tent completely and get the most accurate PPFD by using our meter. While for other meters, you must open one side of the tent to do it, so the light will leak out.. You can recorded the PPFD data for different location by grids and calculate the average.. Can calculate the DLI if the PPFD is stable all the way.. We use Vsensor APP to instead of TUYA APP in 2023 now, more simpler and safer..
