Engineered with immersion correction and a rugged waterproof sensor, it delivers highly accurate photosynthetic photon readings (400-700 nm) with less than 5% uncertainty and minimal calibration drift. Trusted by experts and backed by a 4-year warranty, this USA-made instrument is the ultimate tool for serious aquatic horticulturists and reef enthusiasts. ## Description Product description Review: Sent used item - Sent me a used item. As soon as I opened it immediately noticed scratches on the sensor and then saw corrosion everywhere including the screws. Very Unsat to spend over $600 on an item to find it was already used. Review: Absolutely nescesary for your marine reef tank. - I bought a cheaper VBR version of a PAR meter on here and didn’t know that it didn’t measure the blue lighting in my tank. I spent several hundred dollars on corals thinking I had a PAR reading. I went to my LFS and asked them and they asked where did you get your par meter and I said desertcart and it’s a VBR meter. Sure as dog doo doo they said it isn’t measuring the blue lighting. Purchased this PAR meter and everything in my tank is booming. Sometimes trying to save a buck isn’t the best option in some cases. ## Features - DR BRUCE BUGBEE: Apogee PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist. - UNDERWATER ACCURACY: The MQ-510 ensures precise PAR measurements underwater by applying an immersion effect correction factor. It measures photons between 400 and 700 nm, providing a single PAR reading in µmol m-2 s-1 with less than 5% uncertainty. Its stable calibration boasts an accuracy drift rate of under 2% per year, unlike hobby-grade meters. - FEATURES: The rugged detector measures photosynthetic photons from 400-700 nm from any light source by taking instantaneous or logged measurements; immersion correction-factor calibrated in for accurate UNDERWATER par-measuring. - RUGGED DESIGN: The sensor head is made of machined aluminum and fully potted, making it waterproof and rugged. The tangle-free cable facilitates measurements over a large plant canopy, while still allowing the user to view the high-contract display screen. NOTE: Handheld-meter display is NOT waterproof - MANUFACTURED IN THE USA: All meters are backed by our four-year warranty and supported by our US-based customer support team. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 2.9 out of 5 stars 13 Reviews | ## Images ![Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Image 1](https://m.media-amazon.com/images/I/71gvVvP9G9L.jpg) ![Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Image 2](https://m.media-amazon.com/images/I/51cRoOck7IL.jpg) ![Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Image 3](https://m.media-amazon.com/images/I/61TC4iVDzaL.jpg) ![Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Image 4](https://m.media-amazon.com/images/I/61Zws2lY3sL.jpg) ![Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Image 5](https://m.media-amazon.com/images/I/51v-Tb8OZwL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐ Sent used item *by M***A on October 15, 2025* Sent me a used item. As soon as I opened it immediately noticed scratches on the sensor and then saw corrosion everywhere including the screws. Very Unsat to spend over $600 on an item to find it was already used. ### ⭐⭐⭐⭐⭐ Absolutely nescesary for your marine reef tank. *by M***. on June 3, 2024* I bought a cheaper VBR version of a PAR meter on here and didn’t know that it didn’t measure the blue lighting in my tank. I spent several hundred dollars on corals thinking I had a PAR reading. I went to my LFS and asked them and they asked where did you get your par meter and I said Amazon and it’s a VBR meter. Sure as dog doo doo they said it isn’t measuring the blue lighting. Purchased this PAR meter and everything in my tank is booming. Sometimes trying to save a buck isn’t the best option in some cases. ### ⭐ Open, Used and Dirty *by R***V on August 25, 2022* I spent over $560 on this par meter only to get a package that was already opened and used. No instructions or no paper work to show the product. Or how to use it. The par meter was dirty and the battery didn't work. I had to replace the battery with the one that was in it because it was crusty like it was dropped in saltwater. ## Frequently Bought Together - Apogee Instruments MQ-510 Full-Spectrum Quantum PAR Meter, for Underwater/Reef Tank Precision Light Measurement - All Light Sources Including LEDs - Polyplab - Professional Reef-Roids - Coral Food for Faster Growth - 150g --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/395399106-apogee-instruments-mq-510-full-spectrum-quantum-par-meter-underwater](https://www.desertcart.gr/products/395399106-apogee-instruments-mq-510-full-spectrum-quantum-par-meter-underwater) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-28*
