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

If these ever actually die or use up the extra batteries I will buy the same ones as replacements. Just replaced the batteries in one and I’ve been using them for 11 months now. The one with dead batteries has been working overtime. It’s in a basement. In Florida. On waterfront property. So it’s been reading 99% humidity the entire time. The poor little thing is probably as exhausted and overheated as I am! I still have one more set of batteries and the other meter is still going strong. I can’t think of the last $5 I spent that lasted as long as this pair of hygrometers! They are probably not accurate enough to conduct college thesis scientific experiments, but they are CLOSE. And that’s all I needed - to get an idea of how the humidity levels in the basement compared to the rest of the house and how those levels change with the seasons and rainfall. I think the humidity readings are more accurate than the temp readings, which sometimes showed ~4• off from the thermostat BUT my purposes are really for the humidity readings. Totally satisfied with this purchase and will buy same ones again if/when this pair quits or the batteries all die. Probably the extra batteries alone are worth the total cost. #battery life excellent #accuracy close enough #happy customer

These little things have been running inside my 3D printing filament boxes to help me check if the desiccant inside is still good. They come in a pair and I only bought one pair to start, then two more after finding that they worked for my application. They come WITH batteries already inside AND replacements which is VERY helpful. I cant attest to their accuracy since I dont have a calibrated hydrometer to check them, but they seem accurate enough. My oldest pair have been running nonstop from 1 October 2020 to now 18 February 2021. I do not know when they will run out.

Id buy it again because there are so many but I did have about 3 or 4 that didnt work. Some also dont match up.

Product exactly as described, came with double sided tape pads, large numbers and easy to read; measurement are consistent between the two within 1 degree and consistent with my side of tank heat indicator strip within about 3 degrees. For the price, this is a reasonable set that will give you a good idea of temp and humidity. May not be exact, but then again... these things rarely are exact. For my purposes, the 1-3 degree difference is not a big deal. Also came with extra batteries which is a huge plus since they are little button batteries and I would have to order more. Now I can change them when they go out and go ahead and order new ones without having to take them out of the tank, see what kind, and then wait several days to get them. Would buy again.

These temp/humidity gauges are perfect for what I need them for, my praying mantis enclosure. So beautifully simple & cheap, but not poor quality! These are very sturdy & very easy to place due to being small. But not so small that you cant read the screen. They are perfect.

Bought these as a backup to my normal hygrometers in my humidors. They are pretty much spot on, and at a great price. I recommend!

When placed side by side they give a different reading...close by about 1 degree but being side by side the reading should be the same and it is NOT.

They are very accurate for the price.

Works well in humidor and wine fridge

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.
