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. .

AS803 Lux Light Meter is used to measure intensities of illumination in Lux or Footcandles, widely used in scenic design, research teaching, industry inspection as well as agriculture researching and illumination control..

FOR SCIENTISTS SERIOUS GROWERS - Designed by world-renowned crop physiologist, Bruce Bugbee, PhD, the MQ-610 ePAR meter is the first in its class among leading scientists and serious growers for accurately measuring the new extended photosynthetically active radiation ePAR from 400 to 750 nm for all light sources.. NEW ePAR RANGE - Laboratory-grade measurement of the newly defined 400-750 nm ePAR has been found to be photosynthetically active beyond the traditional 400-700 nm PAR. Much of the transformative work to define the ePAR range was conducted by Dr. Shuyang Zhen and Dr. Bruce Bugbee. The MQ-610 can accurately measure far-red photons 700-750 nm, found in many next-generation LED fixtures, the sun, and other light sources, which cannot be measured by traditional PAR meters.. QUALITY ePAR METER - Unlike cheaper LUX or footcandle sensors which are sometimes marketed as grow light meters, but are meant for measuring light for human vision, our meters feature a laboratory-grade ePPFD extended photosynthetic photon flux density optical detector precisely calibrated to measure the light intensity in mol m-2 s-1 of the specific color wavelengths including far-red emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants for photosynthesis.. EXTREMELY ACCURATE STABLE - Precisely measures and combines the intensity of all photons between 400 and 750 nm to give a single ePAR reading in mol m-2 s-1 within 5 uncertainty. Our ePAR meter has a stable, accurate calibration with an accuracy drift rate of less than 2 per year.. RUGGED EASY TO USE - The sensor head is machined aluminum and potted solid with epoxy for years of use in harsh environments, including underwater. The handheld meter is attached by a cable and displays real-time readings, records samples, and logs average intensity and daily light integral DLI measurements. Unlike the sensor head, the handheld meter is not waterproof..
