There's a problem loading this menu right now. Amazon, Ebay, and a few other internet shopping sites sell Lux meters from China, specifically the LX1010B model, which looks like a PAR meter, and does exactly the same thing, but reads out in Lux units instead of PAR units, and is not waterproof, so it can't be dunked in an aquarium. Mars Hydro SP 3000 Review. PPFD stands for Photosynthetic Photon Flux Density. The meter has a sample and log mode, and will record an integrated daily total in mol m-2 d-1. The PPFD of sunlight is between 900 and 1500 μmol/m²/s. This is a great feature unique to the Apogee Mq-200. If we were to track the amount of PAR emitted over a period of time, we would then be provided with the Photosynthetic Photon Flux (PPF) of that light: the number of moles of photons expressed within the 400-700nm over time, in umol/s… Sample mode will record up to 99 manual measurements. fruit-bearing short-day plants indoors, PPFD values of approx. Since the optimal average photon density is 700 µmol/m 2 (PPFD), the optimal number of photons is 700 µmol Usable PPF per square meter. $36.99 $ 36.

Sample mode will record up to 99 manual measurements. Order) 2 YRS . The sample mode stores up to 99 measurements. The units for PPFD are micromoles per meter squared per second (written as μmol m-2 s-1). … PAR stands for “photosynthetically active radiation” and can loosely be translated to “emitted light”. Every 30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory. If you want to find out the true light intensity of a lamp over a designated growing area (e.g. Quantum Light Meters are calibrated to display PPFD. The meter can store up to 99 averages.
