Small Aquarium Underwater Ambience with Very Light Bubbling

  • FOR SCIENTISTS & SERIOUS GROWERS - Designed by world-renowned crop physiologist, Bruce Bugbee, PhD, the MQ-510 full-spectrum underwater quantum meter is the premium tool of choice among leading scientists and serious growers for accurately measuring the photosynthetically active radiation (PAR) underwater..
  • MEASURING PAR IS CRITICAL - An accurate PAR meter is critical 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 ....
