    • Great thermometer for plant environment control
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.

    • Almost perfect
Review Image by Andy Andy
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!!! ... show more

    • OK
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 ... show more
