Nice & useful tool

I user this to regulate the baking area for my turtles and it really helps. No guesswork. Just press trigger, aim, release trigger and look at readout. Have made the cats off my pets very easy.

Great thermometer. The VPD ability is key as I need a very specific range for my plants. It also allows me to know leaf surface temperature, which is another key variable for environmental control. Easy to use and read, great value for the price.

It is quite technical for the beginner such as myself, however the manual explains it all quite well. I love it!

Another great product from AC Infinity.

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!!!

Works great as intended! Worth the money

0 stars this is a piece of junk I expected better from ac infinity this don't take accurate temps or humidity pointed it right at humidifier while was on full blast said 45% never would raise higher temp was always wrong as well just a oversized laser pointer don't waste your money or time

Humidity takes forever to adjust (like a whole night) and it's 10% off... Absolute rubbish

I was surprised these guns weren’t dearer because some guns that only read temp are more expensive. It seems well made too I’d definitely say they’re worth the money!! If you grow using vpd as a guide one of these guns is a must it takes all the guesswork out and the plants love the temp and humidity I’ve set it at

Sehr cool das Gerät, Blatttemperatur unterscheidet sich zur Raumtemperatur . Wie ich feststellen konnte macht die Lampe auch noch mal ein unterschied.

It helps me dile my grow in perfect home growers for the win

All perfect, I love Ac infinity quality products
