Apogee MQ-510 Full Spectrum Underwater Quantum Meter

FOR SCIENTISTS & PROFESSIONAL GROWERS - Designed by world-renowned crop physiologist Bruce Bugbee, PhD, the MQ-510 full-spectrum underwater quantum meter is the premier tool among leading scientists and serious growers for accurately measuring photosynthetically active radiation (PAR) accurately underwater.

PAR MEASURING IS CRITICAL - An accurate PAR meter is critical for measuring the intensity of light used in accurately growing plants and other photosynthetic organisms in greenhouses, growth chambers, farms, gardens, aquariums and other agricultural systems. Our underwater quantum meters are specially designed to measure the intensity of light underwater for biological, chemical and physical processes in natural waters and aquariums.

UNDERWATER ACCURACY - Underwater PAR measurements may be low when a quantum sensor is calibrated for air. The MQ-510 applies an immersion effect correction factor to get instant, accurate measurements underwater. Accurately measures and combines the intensity of all photons between 400 and 700 nm to give a single PAR value in µmol m -2 s -1 within an uncertainty of 5% underwater. Unlike hobby-grade PAR meters, our meter has a stable, accurate calibration with an accuracy deviation of less than 2% per year.

QUALITY QUANTUM METER - Unlike cheaper LUX or footcandle sensors that are sometimes marketed as grow light meters, but are intended for measuring light for human vision, our meters have a laboratory quality 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 used by plants and coral for photosynthesis.

ROBUST & EASY TO USE - Quantum sensor head is made of aluminum and cast solid with epoxy for years of use in harsh environments, including underwater. The handheld meter is attached with a cable and displays real-time measurements, records samples and records average intensity and daily light integral (DLI) measurements. Unlike the sensor head, the handheld meter is not waterproof.

THREE MEASUREMENT MODES - The meter has a spot measurement, sample and log mode and records an integrated daily total in mol m -2 s -1 . Sample mode records up to 99 manual measurements and Log mode turns the meter on and off to take a reading every 30 seconds. Every 30 minutes the meter calculates the average of the 60 second measurements and stores the average value in memory, up to 99 averages. Once full, it overwrites the oldest measurements with new ones. A daily light integral is recorded from the 48 average measurements for a day's worth of measurements
