20. FUTUREHORTI
It can test the illuminance value in small spaces or places that cannot be touched by people Because the main spectra of led cmh hps and sunlight are different human eyes and plants have different perception abilities for these light sources Fh100 is specifically designed for different spectra to measure the most accurate lux or ppfd When testing because you dont need to hold it you can avoid that the light is blocked by your body
When testing ppfd in a closed tent you can close the tent completely and get the most accurate value 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 and you cant get the most accurate value Save manpower For example to test the illuminance of the light source at different distances or different powers with fh100 only one person can complete it instead of two people
