For Scientists and Serious Growers
The MQ-500 full-spectrum quantum meter is the premium tool of choice among leading scientists and serious growers for accurately measuring the photosynthetically active radiation (PAR) from all light sources. An accurate quantum light 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 other agricultural systems.
Quantum Light Meter
Unlike commonly available LUX or footcandle meters used 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 colour wavelengths emitted by LEDs, HPS, MH, sunlight and other light sources that are utilized by plants for photosynthesis.
Rugged & Easy to Use
Quantum sensor uses a precision silicon photodiode detector, a custom optical filter, and an acrylic diffuser all housed in a self-cleaning, dome-shaped, anodized aluminium sensor head. The sensor head is 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 blue sensor head, the handheld meter is not waterproof.
Extremely Accurate & Stable
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.
Three Measurement Modes
The meter has a spot measurement, sample, and log mode and will record an integrated daily total in mol m-2 s-1. Sample mode will record up to 99 manual measurements and log mode will power the meter on and off to make a measurement every 30 seconds. Every 30 minutes, the meter will average the sixty 30 second measurements and record the averaged value to memory, up to 99 averages. Once full, it will overwrite the oldest measurements with new ones. A daily light integral will be recorded from the 48 averaged measurements for a day’s worth of readings and is downloadable via Apogee AC-100 cable.
How is the MQ-500 different from previous Apogee quantum sensors?
The MQ-500 is a full spectrum quantum sensor with an optimized, highly accurate spectral measurement range of 400-700 nm, which can be seen compared to our older "original" quantum sensor in the graph below. The improved spectral response of this new meter greatly increases the accuracy of LED measurements when compared to their previous "original" models.
