- PREMIUM QUALITY: The MQ-500 is the premium PAR meter of choice of research scientists and serious growers who need absolutely accurate PAR measurements season after season. Budget PAR meters can start out as accurate, but readings can drift up to 50% or more after one year due to the degradation of the cheaper, low-grade optics. This unpredictable accuracy can lead to disastrous crop results and inconsistent grows.
- FEATURES: Ruggedized, precision optics accurately measure the total of all photosynthetic photons from 400-700 nm from any light-source ensuring crops receive the recommended light intensity needed for maximum and consistent yields, grow after grow. The meter reads current instantaneous intensity, can log measurements over a 24 hour period (DLI), and collects and stores sample readings from different spots of the plant canopy for PAR mapping.
- MEASURE PAR NOT LUX: LUX or Foot-candle meters are designed to mimic the human eye's response to light and are irrelevant for plants. Cheap LUX meters are mass-produced for use in photography and are often improperly marketed as PAR meters for plants. Authentic Apogee PAR meters have been used for nearly all modern plant lighting research and are recommended as the standard by most lighting manufacturers.
- RUGGED DESIGN: The sensor head is made from high-grade machined aluminum and fully potted with electronic epoxy making it impervious to water and rough use. The tangle-free sensor cable allows for measurements of PAR far out over the plant canopy while still being able to read the high-contract display screen.
- DR BRUCE BUGBEE: For 30 years, Apogee PAR meters have been designed and refined by Dr Bruce Bugbee, a world-famous crop physiologist, leading authority on plant photobiology, and leading advisor to lighting manufacturers. Authentic Apogee PAR meters have been used in virtually all modern plant lighting research and are recommended as the standard meter by most lighting manufacturers.

- 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 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 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.

Then, our experts used criteria that are recognized in the business to evaluate them according to their quality to price ratio, allowing us to choose the top quantum light meters on the market right now!
The selection of the goods is not arbitrary. Before creating a list, we take into account a number of factors. Below are some of the criteria discussed:
Brand Value: What happens if you choose a dubious brand just because it appears to be a good deal? So the likelihood of receiving a product with a short shelf life increases. That is due to the fact that well-known brands have a reputation to uphold, while others do not. Top quantum light meters brands strive to provide some distinctive traits that set them apart from the competition. So, hopefully one or more of the items on our list will be perfect for you.
Features: Useful features are all you need, not tons of them. We consider the important aspects and select the top quantum light meters based on those.
Specifications: Numbers always help you measure the quality of a product in a quantitative way. We try to find products with higher specifications, but with the right balance.
Quality: A product’s quality may always be quantified with the aid of numbers. We look for goods with better standards that strike the proper balance. The best quality product that gets highly appreciated and recommended by experienced users.
Customer ratings: Would it be accurate to suggest that the quantum light meters were used by hundreds of customers before you? Superior ratings indicate that many customers had better service.
Customer Reviews: Like ratings, provide you with accurate and reliable information about the product from genuine customers. Customer ratings are very important to all of us because they contain accurate and reliable information about the customer service we received from several hundred customers.
Seller Rank: This is very intriguing! Not only do you need a good quantum light meters, you also need a product with rising sales that is trendy. It accomplishes two goals. First, the expanding user base proves the quality of the product. Second, given that number, producers must be able to offer greater quality and after-sales support.
Value: You get what you pay for, they say, so consider the value. Cheap isn’t always good and expensive isn’t always bad. However, that does not imply that spending a lot of money on a product that is flashy but underwhelming is a good idea. Before adding them to the list, we make an effort to evaluate how much value you can get for your money from your quantum light meters.
Durability: Durability and reliability are closely related concepts. You will benefit from a strong and long-lasting quantum light meters for months and years to come.
Product availability: Products come and go, and new ones replace the old ones. Most likely, a few new features and required changes were made. What use is it to use a supposedly good product if the maker no longer supports it? We make an effort to highlight products that are current and offered by one or more trustworthy sellers, if not more.
Negative Reviews: Yes, we do take that into account as well! The goods with the majority of bad reviews are filtered out and disregarded when we choose the best-rated one on the market.
These are the standards by which we selected our quantum light meters. Do we end our process there? Hell no. The most crucial fact about us that you should be aware of is that we regularly update our website with current and pertinent information. We have one more layer of filtration since we place the greatest importance on reader satisfaction.
