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

Definitely worth the money you get two temperature/humidity gauges 4 sets of batteries and two velcro tapes. I am highly impressed both gauges were pretty much spot on and also were within 1 degree for temp and 1-2 points off humidity compared to my zoomed hydrometer. I want to note that the probe it is placed at the bottom of my gecko tank so there naturally would be a little bit of a discrepancy between the zoo med and the two aik tryee mini hydrometers. My zoo med hydrometer was about $10 this was half the price and you get 2 hydrometers plus extra batteries I wish I came across this earlier. I am happy with my purchase and will be purchasing more for my various reptile tanks.

I place them side by side and they give different readings. I understand that there might be a small difference as the add says but not a significant difference in measures of humidity and temperature. So if you are looking for accuracy these are not it. I may return them.

I purchased these gauges to keep a watch on the humidity in my guitar cases.

I have 4 of these and they all work great. They all are within like 1 degree accuracy of each other. I use them for my cigars. The batteries died on one and I didnt know these had replaceable batteries. So I went and bought new batteries. Its a tough time changing them. Well the thing doesnt work now. Sometimes it will have power to it but as soon as I put the battery cover back on, nothing. So instead of replacing batteries, considering the price, Ill just buy another one and maybe Ill be able to change the batteries on my other units.

They stay within a percentage point of each other, so they are accurate, or equally inaccurate at least. But I have another hygrometer in the same room and it agrees with these. So, all good.

Good cheap Hygrometer, The double sided tape it comes with is poor quality, use Gorilla tape instead.

I wanted a thermometer for upstairs and another for downstairs, but only one consistently works. The other one will occasionally show a reading, but its different from the first one even though they are side-by-side.

I got these for the inside of my bearded dragons tank, and they adhere to the tank, easily or easily to read seem to be accurate

They are very accurate for the price.

I ordered these digital Hygrometers thinking they would be somewhat accurate within a percentage point or so. I decided to do the salt test to see if they would read at 75%. As you can see from the photo after 24 hours the salt test proved that these are both inaccurate. One read 73% (not too bad) the other read 70% (way off). You do get what you pay for. I was hoping to be able to re calibrate them after I found out what the actual humidity level it was reading but according to the company all you do is take out the batteries and put them back in again! I did do this before I administered the test. Please be aware that you should do a salt test to see how far these are off. I wouldnt necessarily recommend these since in some cases knowing the humidity within 1% can be extremely important for some people. You should be able to calibrate them as well.
