## Description

The Phantom PHOTOBIO Advanced Quantum PAR Meter provides accurate and cost-effective measurement for any light source used in horticultural applications. The Advanced Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a positive proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis, important for maximizing crop yield.

Review: Great. Definitely buy - Works amazingly well fir the price. Was not expecting how quickly it stabilized and have accurate readings. Nice little storage case as well
Review: Excellent Light Meter with Superb Carrying Case - I'm thoroughly impressed with this light meter! From the moment I took it out of the box, I could tell this was a high-quality piece of equipment. The carrying case is absolutely fantastic - it's sturdy, well-padded, and has a sleek, professional look. But the real star of the show is the light meter itself. It's incredibly easy to operate, with an intuitive interface and clear, readable display. The buttons have a nice, tactile feel and the whole device just feels solid and well-constructed. Taking light readings is a breeze - it gives me accurate, reliable results every time. What I appreciate most is how user-friendly this light meter is. After reading substantially about taking measurements from LEDs versus sunlight, I was a bit intimidated by light meter. But this one has made the whole process simple and straightforward. The instructions are clear, and I was able to start using it right out of the box. Overall, I couldn't be happier with this purchase. The combination of the excellent carrying case and the easy-to-use, make it a no brainier. I'd recommend it to photographers or plant enthusiasts of any skill level who want a dependable, convenient light measurement tool. This is quickly becoming an essential part of my houseplant and growlight management.

## Questions & Answers

**Q: Will the remote sensor work under water?**
A: By default no. However i bought this to measure PAR in my reef tank. I tried a ziplock bag approach and the bag let some water in- but i found a trick that so far lets me fully submerge the sensor eye and protect it and measure PAR. I will add this trick is not supported by the manufacturer and will void your warranty but here goes:

1) plug the long straight cord into the sensor eye
2) use clear silicon aquarium safe caulk around the sensor eye; seam perimeter around the entire sensor; screw holes in the back of the sensor ; caulk around the female receptacle of the sensor while the cord is plugged in.
3) let that caulk cure for about 48 hours
4) get a small ziplock salad dressing container- just big enough to accommodate the sensor.
5) super glue the sensor to the bottom inside of the ziplock container
6) go to lowes or Home Depot and get 1 quart of clear epoxy resin.
7) mix a small batch of epoxy resin per instructions.
8) pour resin in ziplock container. Let the resin completely cover and surround the sensor eye.
9) let resin cure for about 24 hours- use scissors to cut away the ziplock container.
10) rinse encased sensor under the faucet.


Voila your sensor is now water proof and can be used under water without damaging the sensor- keep in mind this is 1000% permanent- once you do this - it stays like this.

But surety beats paying $500 for an apogee PAR meter. And you can still use it as a plant PAR meter as well.

**Q: What is the calibration uncertainty for this light meter?**
A: Absolute calibration: +/-5%

**Q: What is the precision of this product ? Do you deliver to Brazil ?**
A: Unsure of accuracy, but it is pretty comparable to the par map on any light I've tried it with

**Q: I'm curious if you would share a sensor response plot? guessing no but worth a shot.**
A: A video showing how fast the sensor responds to light intensity?

### ⭐⭐⭐⭐⭐ Works great
*by H***H on November 9, 2025*

This PAR meter which I have had for some time now has held up very well and it has worked perfectly. It has really improved on the grows with knowing exactly where the PAR levels are at for every stage of the grow. I would definitely recommend this product, and I will buy again in the future when this one eventually breaks.
