Par or ppfd is a must for any botanical enthusiast. I grow my own medicinal herbal botanical produce. The unit is very accurate in reading ppfd. The unit allows me to keep daily accurate readings. No more playing with light heights and dimming switches. Takes the guess work out of the grow and make it quantifiable which I enjoy. This unit was used, no manual, case or other accessories. It was ready to use out of the box. No instructions needed. The unit was very clean with no viable signs of damage. The price was so affordable that I couldn’t pass it up. I appreciate the seller very much for the price and fast shipping. And I can’t forget about the cool factor of actually having and using this thing. It is cool to use it throughout my grow

As an indoor hobby grower, knowing The PAR output of my powerful new LEDs allows me to dim or adjust their height from the plants without burning or low light levels. I find that this meter is an accurate and very useful tool. It is inexpensive but not cheap. A great value when compared to other well known PAR meters.
