Par Meter High Precision PPFD Meter, Par Meter for led Grow Lights 400-700nm Wavelengths Par Light Meter with Data Logging, Calibration Function, PPFD Meter for LED Grow Light, Greenhouse, Plants

Has worked flawlessly for over a year. Much more useful and accurate than the lux meter phone adapters and not very expensive, at least pre-tariff when I purchased.

Well worth it

Easy to use and does what it says all in all very good quality and product.

Looks good, works good

Works great, gives you a reference point to adjust lighting. Wish the screen was brighter.

I can not get this to work with led. Works fine with natural light. I can hold it inches underneath 300 watt led and read 4-5 hundred ppm and 3-4 hundred at edge of tent. Or sometimes other way around. Only varies1-2 hunded from light at top of tent to bottom. Should be 3000 ppm plus at light and 900 ppm plus at edges. This only weights a little over a ounce. There is nothing in it like a empty shell. It reminds me of something in the toy section of a dollar store. The ones I’ve seen cost $600 or more and I can not afford. I do not think you can get one to work right for under this. This is the 3rd different kind and I had to return all 3. There is a reason grow shops do not sell these $5.00 things and should have been a heads up for me. The packing is a little generic plain white box with no writing or pictures of what is inside. Can you spell China?

My plants now have a great source of light because of this. I can't live without it. Well well worth the money 💰 and easy to use.

Works!

My wife keeps and propagates all kinds of plants, and since this is done indoors, she has all kinds of plant grow lights at her disposal. The challenge, however, is that having a grow light doesn't mean much if it doesn't produce the right amount of "PAR" (Photosynthetically active radiation), and knowing the amount of PAR for any given light at any specific distance is pretty important. What I like about this PAR meter is just how simple it is to use. It has no complicated features or strange settings to leans. And calibration takes a few seconds. By the same token, some people might want more out of their light meter, but for plants, this is what you want. Included in the kit are 2 x AAA batteries, a manual, the sensor (with a 1/4" tripod mount hole, if needed), and two types of cables. The twisted cable is ideal if you're using this as a handheld meter, while the longer cable is great if you're setting the sensor up somewhere long term. This unit does have a logging feature, which can be handy. As far as I can tell, there's no way to export the log. The readings (in μmol/m²/sec) are fast and seem to be quite accurate. We've tested several lights already, and it seems to be in line with another PAR meter she uses. At the time of this review, this meter is listed for $149.99. This is in line with several other similar PAR

Absolutely fantastic piece of equipment work perfectly and I’m so glad I chose this one 🌟🌟🌟🌟🌟👍😁

Simple and effective light meter, works great!
