AC Infinity infrared the functionality of this item is awesome the temperature accuracy is always on point it’s also very easy to use & It’s built with quality it’s worth the value for the money spent

Great tool to up your game. Perfect quality. Comes with everything as advertised.Only negative I can think of is the instructions it comes with are not clear regarding how to pull the trigger... I mean: should I keep it pressed for a certain amount of time to get the reading or is just a quick press and release enough?Any how, this tool helped me realize I had a way bigger temp diference between leaf and amb temp than I thought and my VPD calculations were a bit off, and it saves me alot of calculating.It's completely worth the money. I got it witha discount, but would pay full price without hesitating.Thanks ACI!!!

Best products and great after sale service

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!

I had a temp sensor made by a power tool company and used it for multiple things. One for checking temperatures for HVAC purposes. I also use it in a lab setting to check the temperature of equipment we use. Most temp guns don’t have a humidity sensor built in which I find great for household & HVAV use. There’s also memory function which is a bonus. It also has the added option to switch between Fahrenheit & Celsius. I have to use Celsius in the lab. Very easy to use and cheaper than the other temp gun I had previously. Would 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 .
