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..

PREMIUM QUALITY The MQ-500 is the premium PAR meter of choice of research scientists and serious growers who need absolutely accurate PAR measurements season after season. Budget PAR meters can start out as accurate, but readings can drift up to 50 or more after one year due to the degradation of the cheaper, low-grade optics. This unpredictable accuracy can lead to disastrous crop results and inconsistent grows.. FEATURES Ruggedized, precision optics accurately measure the total of all photosynthetic photons from 400-700 nm from any light-source ensuring crops receive the recommended light intensity needed for maximum and consistent yields, grow after grow. The meter reads current instantaneous intensity, can log measurements over a 24 hour period DLI, and collects and stores sample readings from different spots of the plant canopy for PAR mapping.. MEASURE PAR NOT LUX LUX or Foot-candle meters are designed to mimic the human eye's response to light and are irrelevant for plants. Cheap LUX meters are mass-produced for use in photography and are often improperly marketed as PAR meters for plants. Authentic Apogee PAR meters have been used for nearly all modern plant lighting research and are recommended as the standard by most lighting manufacturers.. RUGGED DESIGN The sensor head is made from high-grade machined aluminum and fully potted with electronic epoxy making it impervious to water and rough use. The tangle-free sensor cable allows for measurements of PAR far out over the plant canopy while still being able to read the high-contract display screen.. DR BRUCE BUGBEE For 30 years, Apogee PAR meters have been designed and refined by Dr Bruce Bugbee, a world-famous crop physiologist, leading authority on plant photobiology, and leading advisor to lighting manufacturers. Authentic Apogee PAR meters have been used in virtually all modern plant lighting research and are recommended as the standard meter by most lighting manufacturers..

DLI-500 FULL-SPECTRUM METER Gives research-grade measurements of PAR PPFD, DLI and photoperiod from 400-700 nm under all grow-lighting used for plants. The meter takes spot measurements and records and displays daily light integral in molm-2d-1 and photoperiod in 0.2 hours increments for up to 99 days.. PARDLIPHOTOPERIOD Measuring and controlling the daily light integral the total photosynthetic photons falling on a plant in a 24-hour period and the hours of light a plant receives photoperiod is critical for optimizing plant health, triggering flowering, and inducing other plant morphology effects. PPFD, DLI, and photoperiod data can be viewed onscreen or downloaded via USB-C for analysis.. RUGGED AND READY TO USE Built tough and rated IP65 to withstand harsh and wet environments. Unit can be placed directly on any level surface or mounted by attaching to commonly available camera tripods, clamps, or stakes using the standard camera-sized -20 threaded port on the bottom.
