6 Pack Mini Small Digital Electronic Temperature Humidity Meters Gauge Indoor Thermometer Hygrometer LCD Display Fahrenheit (℉) for Humidors, Greenhouse, Garden, Cellar

Purchased 6pk of these and when I opened up the box and laid them out on the desk, each one had a different reading in terms of humidity and temperature. They were off as much as 5 degrees and 6% humidity. I then placed them within an inch of each other (two rows of three) and checked them 6 hours later. They were much closer, only a degree or so off and 1% humidity off. A few of them read the same. Am using them for a few humidors and tubidors I have created, so they are close enough for me to work with.

I got this so we could know what the humidity was in each room. It servers its purpose well in that regard. The humidity numbers are nice and large and can be easily read as you walk by. The temperature reading, on the other hand, is much smaller and more difficult to see. But as I said, I got it to read the humidity not so much as the temperature. So keeping that in mind it works just fine for my needs. The humidity reading is celebrated the same on all the units when they are in the same room. The same goes for the temperature reading, though I do get a -2 degree reading when compared to another thermometer in the house. No way to really tell which one is off though without a third reading from another source. Overall, I'm very satisfied

I purchased a 6-pack to measure the relative humidity in sealed bags of filament. All of the meters worked and had the same values for humidity and temperature. The temperature measurement matched my AcuRite thermometer.For $2.10 each I could not have gotten a better value.I'm not sure why Amazon has a Rate Feature for 'warmth': I gave this product three stars in this area because they did not make the room feel any warmer ;)

The sensors worked well, but they were just a bit off on Temp & Humidity.Not majorly, but a bit. Of the 6, 3 were off a degree or two on Temp and half a degree on Humidity, they were all in the same environment. The other three were accurate.I'm using them for a microgreen growing tower. Having a Temp and Humidity sensor off by a degree or so isn't a major issue.Overall I'm Happy!

These are terrible temperature and humidity sensors. The temperatures average 3-4° degrees of in both directions compared to my high-end pyrometer that measures accurately to 0.1°. The humidity function appears equally bad.But that’s ok! If you just need a ballpark number, they are awesome! Temperature AND humidity for $2 a piece is hard to beat compared to highly accurate temperature only at $100.I have a pair in an airtight box of 3d printing filament (it’s very moisture sensitive), another pair in a micro greenhouse for this springs vegetable sprouts, and another unit sitting atop my house thermostat (for personal amusement). They all work great for what they are.

Easy to read small toys with big display. All readings are different but they do within the ranges advertised (<4F, <10%).This is the first time I received electronic devices that come with batteries already functioning without the need to remove a thin piece of battery shield first. It gives an impression these might be used or returned items.

I bought these to monitor the humidity of my medicine. I placed all six into a sealed bag overnight with a 58% Boveda pack. The next morning I found that they were all within 2% of the 58% target, for me that is plenty accurate. I also found that their temperature readings were within 1.5° of each other. The only problem I had was that one of them was erratic at first, it would work, then it wouldn't. I found the battery door not completely closed and that corrected the problem. All things considered I find that paying well less than $2 each is a steal!

These are not super accurate at all but give you a great about reading at a glance. I use them with my animals and if anything looks off then I double check with my higher quality gear but so far all have works pretty much within a few degrees of each other. I wish the temp was the bigger number but for this price it can’t be beat.

This item is not accurate at reading RH at all!

All works well!Thanks

Works great. Better quality than I expected!. Fits in mason jars

Thanks, happy customer.
