Plant and ambient temperature are different. This shows the difference. Very useful. Everything from AC Infinity is extremely high-quality. I’ve never been unhappy with one of their products.

WORKS GOOD BUT YOU HAVE TO LEAVE IT IN THE TENT YOU WANT TO CHECK IF YOU DONT THEN WHEN YOU TAKE LEAF MEASUREMENT AND IT CALCULATES ITS TEMP AGAINTS ABIENT TEMP YOULL BE OFF ON VPD OTHER THAN THAT WORKS GOOD , also helps to have the 69 pro so you can more accurately calibrate it i used 2 different hygrometers i know to be on to manually adjust mine. so far after 2 weeks use and leavening it in tent for15 to 20 mins before checking vpd/ it works good laser dots are not bright enough but still well worth the money

I’ve been using the AC Infinity VPD Thermometer for a while now, and I absolutely love it. It’s super versatile—I use it in my grow tent, clone domes, and even my tortoise’s enclosure. The readings pop up almost instantly, and they feel really accurate, which gives me peace of mind. It’s compact and easy to use, so I can carry it around and switch between setups without any hassle. Honestly, this little tool has made monitoring my setups so much easier. If you’re looking for something reliable and convenient, this is it!

Amazing product, would definitively buy again and highly recommend!

The laser dots were hard to see under the grow lights . My cheapo that I already had does not have a VPD calculator but you can see the dot. Pass .

This took the guess work out of indoor growing for me, and serves as a second opinion when I want one! Actually a whole new level of precision measurement you can count on that also does all the VPD calculations based on the leaf temp!
