Small Aquarium Underwater Ambience with Very Light Bubbling
...al for measuring the intensity of light used in the precision growing of plants and other photosynthetic organisms in greenhouses, growth chambers, farms, gardens, aquariums, and additional agricultural systems. Our underwater quantum meters are specifically designed to measure the intensity of light underwater for biological, chemical, and physical processes in natural waters and aquariums..
UNDERWATER ACCURACY - Underwater PAR measurements can read low when a quantum sensor is calibrated for air. The MQ-510 applies an immersion effect correction factor to get instant, accurate measurements underwater. Precisely measures and combines the intensity of all photons between 400 and 700 nm to give a single PAR reading in µmol m-2 s-1 within 5 % uncertainty. Unlike hobby-grade PAR meters, our meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year..
QUALITY QUANTUM 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 PPFD (photosynthetic photon flux density), or “quantum,” optical detector prec....
