Small Aquarium Underwater Ambience with Very Light Bubbling

  • 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 precisely calibrated to measure the light intensity in µmol m-2 s-1 of the specific color wavelengths emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants for photosynthesis..
  • RUGGED & EASY TO USE - Quantum 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..
