Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

Greetings! I have tested the two temp+humidity meters that I received as part of this order. I compared temp with several other certified thermometers. Unfortunately, the temp readings from these meters are higher by 10 or more degrees F. I would be grateful for advice on how to calibrate these meters. It would be great if I can exchange my current meters for ones that work accurately. Thank you!

Got these for my incubators. They seem pretty accurate. Theyre small, but easy to read.

I use them in my humidor and they work great as a supplement to my analog one. They are always within a degree of each other so I am ok with the variance. They are so small so next I will add some velcro to the back and on the humidor so it can stay. I forsee alot of life from these and if not, they were cheap enough that I would buy again. Perfect for what they are made for.

I grow plants in a tent, and have to check the humidity levels. These are a great value, but they dont last very long. One lasts, about the time of each grow to harvest, so I have to buy a new pair, about once per year, if I do two harvests per year, but these dont cost very much, so I think thats fine The downside is the adhesive tape, barely stays on, so be careful where you put it, or use another adhesive. it also makes it near impossible to change the battery, but these dont last long, so that isnt much of an issue The display is really easy to read, and its very accurate. Thats why I dont mind replacing them every year. These are cheap, but the value of accuracy, is paramount when growing things in a tent

I bought 2 of the mini hygrometers and they are giving the same readout that I’m getting from my larger, costlier devices. The size is perfect for placement into mason jars. The additional included batteries were a nice bonus too! There are what appears to be clips on the side that I am unsure of how to use, but am happy with placing them either with the included double sided adhesive stickers, or simply standing/laying down.

This 2-pack of combo hygrometer (measures humidity) + thermometer are small, light, and seem to work well (placing them near each other and a 3rd model of a different brand, the readings are not identical but are fairly close, within about 0.5 degrees in temp and 1–2% humidity. They are also a great value, and come with batteries pre-installed (requires 2 each) PLUS comes with 4 spare batteries (one set for each unit). The only downside is the mounting. They DO come with small pieces of double-sided 3M tape (another nice touch), BUT using it to mount them would (a) block the battery compartment on the back and (b) may leave sticky residue on your glass surface. It would be great if they had with a small loop so they could be hung or a small hole to use a suction cup. But if youre OK with that quibble and dont need perfect accuracy, they are a great value and do the job.

Both worked fine and accurate

Ordered twice at different times, four pieces total. All placed in a sealed container at the same time. After twenty four hours- Relative humidity readings dead on with each other - 70%. Temperature readings within 0.4 degrees, three reading 73.0 degrees, and the fourth reading 73.4 degrees. Conventional thermometers included in the same container read 73.1 and 73.4 degrees. Thats pretty good accuracy/repeatability considering that the units cost less than $2.50 each. For all those complaining about accuracy/repeatability, what do you expect for less than $2.50 each. Youll be spending substantially more for units that use a more accurate sensor and are individually calibrated to give more accurate readings.

I use these in my jars to monitor the humidity and it works for what it is but on the back where the battery enclosure is you push it down and slide it to open or close it and the it holds the battery in and pushes it against the connectors and if the door is loose the battery wont push against the connector enough resulting in the screen being faded its nothing serious I just used a little piece of tape and put it in the back side of the door to create more pressure, pushing the battery more against the battery terminal.

Smaller than I expected (read the description, duh), but that actually works better for my purposes. Two reptile enclosures, two hygrometers in the pack, win! I also appreciate the extra batteries and the double-sided tape. The only issue is that the tape will cover nearly the entire back, including the battery access, and I cant see that going well when I have to replace the batteries. I cut the tape down, but am fairly sure they wont stay stuck for any length of time. And you probably dont want to cover the little holes with the tape, either. Great value for the price!
