I bought a quantum sensor on the Amazon.com from China Mainland. After waiting 2 weeks, I finally got this equipment. It cost me near $400. I do not know this good or not, evenmore there is no sufficient information on the net.
From the Amazon comment, seems not good, also checking on the Youtube, there are 2 videos to be watched only. With information asymmetry, everyone can not make a good decision.
Now I unbox this Quantum Sensor for your reference.
This product describes on the website:
Sun System PAR Meter comes with an integrated sensor to measure photosynthetic active radiation (PAR). Use inside with Sun System grow lights or outside with natural sunlight. Simple and easy to use. Compact size with integrated sensor. 1 year warranty. Sun System PAR Meter with remote sensor measures photosynthetically active radiation (PAR). Use inside with Sun System grow lights or outside with natural sunlight. Simple and easy to use. Compact size with remote sensor. 1 year warranty.
Nothing can help, right!!?
Here is info from Amazon. Shipping address on the package.
Open the package box, there is a really small box inside. Waiting for 2 weeks, it comes in front of me.

Order info, with tax near $100. Felling not good!!!

I can not find how to install the battery into the equipment, I sent message to Sun Supply, but no reply. How they can do this!!! Bad experience. After removing the back cover, I do not how to insert the battery, due to we have to know the "+-" inside.

After reading the manual, I got confused about this product, it said it can test PPF? But for this item, it can test PPFD, not PPF. As I watch some videos on the Youtube. Understanding the spectrum response, thanks Apogee.
