Review on 🌊 Revolutionize Your Underwater Measurements with the Quantum Apogee Full Spectrum Meter MQ-510 by Tony Wylie

Anyone familiar with lighting and plants knows that PAR is a way of measuring how much light a plant is actually receiving. This device measures just that, accurately and very easily. Unfortunately, I find this product a bit pricey for what it really is - it seems like you end up paying only for the quantum sensor itself, and very few resources have been invested in developing the updated handheld device. I ended up buying a used mq500 version of this unit from a friend at a much better price. For that I give 4/5 instead of 5 stars.
