## Overview

The LGBQM2 Advanced Quantum Sensor PAR Meter by PHOTOBIO is a portable, highly accurate device designed to measure photosynthetically active radiation (PAR) within the 400-700nm wavelength range. Ideal for horticultural professionals, it records up to 99 readings and includes versatile connection cables, enabling precise monitoring of light intensity to maximize photosynthesis and crop yield.

## 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: Got for a friend - He said they worked well, I dont know about photography so cant say more.
Review: Top meter - Works very well

## 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?
