PAR Meter for Reef Tank Waterproof PAR Meter Aquarium IP68 Quantum Sensor PPFD Meter Data Logger, Full-Spectrum Quantum PAR Meter with 79" Cable and 37" Solid Telescopic Pole Included

Great price and the product works well. When you compare it to the gold standard in aquarium par meter (Apogee MQ-510) you need to take the reading and multi-ply it by 1.25 to get the same reading as the Apogee. But for the price and knowing your PAR, it is an outstanding product.

Bought for reef tank, works as it should. Got me dialed in.

After reading reviews and saw that people claimed this Par meter being a fraction of the price of an expensive Apogee meter, was only 5-10% off in accuracy in comparison, I bought it. I found out that this was WAY off in terms of Par reading. At first I thought my ReefLED 50 was defective, because the readings at the surface and all did not even come close to that of a what RedSea claimed their light performance was. It was way off. See attached photo. I even calibrated the sensor many times in the dark, completely covered. It made no difference. The readings are unreliable and cannot be used, it’s too far off.

The number that you get for par times it by 1.6 and that’s the real number of par

Doesn’t give accurate Par Readings in reef Tanks

It seemed to work well but I’m a novice so can’t really comment on if it would meet the needs of specialists. I won’t use it much now that my tanks are happily established. But it was helpful setting up (based on my limited experience). No regrets….

This PAR meter is accurate for Reef lighting measurements for the average reef aquarium hobbyist. Probably not research grade, but most certainly good enough for the hobbyist.

First one came in and didn't work. It was replaced. Second one came in used it two time scenes January. Go to use it the 3rd time and it's not reading anything. Was cleaned and dried off after both uses. So at this point I could care less about the warranty because I dont trust the thing to last. So keep your money

Alles in Ordnung

It’s a very handy tool. It’s easy to use and it’s very accurate. Well worth the money.

Ik heb de meter 1x getest daarna is hij weer in de doos teruggegaan. Dus ik vindt dat je wel kan stellen dat de meter nieuw is Toen ik hem daarna weer wilde gebruiken deed hij het niet meer . Ik heb contact gehad met danoplus en zij stelde dat ik er verkeerd mee ben omgegaan, Hier ben ik het niet mee eens,ik heb de sensor eigenlijk maar 1x in het water gehad en niet meer De sensor vervangen moet worden voor usd 52,60 Dit ga ik natuurlijk niet doen en danoplus krijgt van mij dus daarom 0 sterren Vriendelijke groeten Robin Huisman

Par mètre, très fiable et précis, plug and play

So helpful and insightful rather than just guessing intensities! I was originally running 4 XR15 blues and an AI blade glow all at 100% thinking the tank didn’t look that bright and PAR output on them is low according to forums. Turns out I was cooking LPS and getting 300 par on the sand. Dialled everything down thanks to the readings from this and LPS is looking better and SPS are still getting 350+. Easy to use, just turn it on and point, not much more to it. Definitely turn wavemakers off to stop surface agitation, other wise you’ll cause light ripples which will make the numbers jump all over. Be mindful of the version you receive. The green dot sticker on the box will indicate which you have with the ones that have the green dot on the front being the newest and most accurate.
