AcuRite 01080M Pro Accuracy Temperature and Humidity Gauge with Alarms, Black

Cigar humidification needs to be very precise, and I have had difficulty getting something accurate. I needed a unit that I could calibrate. I have tried multiple units that claim to offer a calibration feature. Unfortunately, they were mostly useless, since the factory calibration was so poor that they could not be adjusted to be within range.Even some of the specialist cigar hygrometers are useless. The only one I found to work was the Cigar Oasis Caliber unit, which is easily adjustable, and of course this one.This unit is a third of the price of the Cigar Oasis, and so I've ordered another two, since I need to monitor several positions within two humidors.It's larger than expected, but this isn't a bad thing. For calibration, you will struggle to fit it into the bag of the Boveda calibration kit. Better to get a larger zip bag and put in 2x 75% 8g packs. This is much more accurate and reliable than a salt test.It also displays one decimal place. It is only adjustable 1% at a time, but it's useful to know the decimal place for calibration purposes.

Very accurate on the humidity reading, & also on temperature. (Tested against my dehumidifier & separate monitor)The lcd figures react very quick to changes compared to my older monitor shown, & so more accurately depict real-time environment. Pretty impressed & the price was good 😌. I’ve been able to see the variations between rooms that we use & those that are not, & air them out as needed, getting rid of humidity & keeping other parts of the house warmer as a result.I’m pretty chuffed with these little beasts. I’ll buy another for the hell of it as I like to know which parts of the house seem more affected by moister, with 2 little girls at home, it’s a good idea to make the house not only comfortable for them, but eliminate any humid/temp issues that is known to affect health/respiratory etc. I’m happy, even if I’m a bit of a nerd for it 😅. Everyone benefits in the end ✅

When you just want a humidity gauge you don't need something that tells you the moon phases do you. This has some other bits on but essentially it's an accurate RH monitor and very good value as well. I use it for where I need a dehumidifier and for keeping a check on areas I am not sure about. Best one at the price.

Happy with the first one, so bought another a few weeks later. When placed side by side they are *very* accurate to each other on both humidity and temperature, so seem well made. Whether they are accurate to the actual temperature is obviously much harder to ascertain, but it does give you a bit of confidence that they are better than the cheaper stuff.Only downsides are that it would be better to have the temperature taking centre stage, more central and prominent. It's also fairly hard to read in low light conditions.

Mainly bought it as a humidity sensor but ended up using more for temperature. Had it for 7 months before I noticed it had stopped working. Now apparently all rooms in the house are 25 degrees night and day and our fridge is 14 degrees. Expected it to last longer than it did.
