ThermoPro TP49 3 Pieces Digital Hygrometer Indoor Thermometer Humidity Meter Mini Hygrometer with Temperature and Humidity Monitor Outdoor and Room Thermometer

It all was completely intuitive, except the button to switch between celcius and fahrenheit being small and on the back. And that worked great once I read about it in the instructions. I love that the batteries are standard AAA, and very easy to replace, including the battery door seeming simple to access, yet secure and reasonably rugged. So cheap batteries, rechargable batteries, etc. are reasonable options for this. Plus, supposedly the batteries last about 18 months (I can't confirm this).I used the modes with it propped up with the fold-out stand on a flat surface and with the magnet on my refrigerator door, and both were dandy. It looks like it would also hang OK for those who want to do that, but I didn't actually try that.There was a little booklet explaining the functions (in reasonable sized print with my reading glasses) and a list of support numbers to call, by country.By getting 3 as a pack, I was able to use 3 close together (as a test) and determine they're quite accurate in both the temp. and humidity readings, as claimed.With a new HVAC system, I wanted a better understanding of the temps at the periphery rooms of my house vs. the central hallway, and re the humidity with the system running, and these handle that well.My only slight criticisms are:1). That the settings for "comfort" re the human face icon are arbitrary and appear not to be adjustable, so somwehat useless IMO. Seems mostly like a marketing gimmick to me. (For example, I'm skinny and cold natured, so "comfortable" to be would be a warmer temp range than the one they chose).2). There appears to be no backlight or option for one, so if it's dark you can't see the numbers at all. Not a big deal, and especially given the batteries last so long (re their claim), but some folks might like that option (which might cost more, take more batteries, etc).Overall, for the price, this was better and more convenient than expected.

I had a dilemma recently, I bought a dehumidifier for my basement. It has a digital display, but I couln't tell if its humidistat was accurate. To test it, I tried verifying with a half dozen other hygrometers I had, and unfortunately, they were all over the map. I decided to purchase this three pack of ThermoPro thermometers/hygrometers. I set them up next to each other in the basement. All three were within 1% of what my new dehumidifier stated, so I guess the dehumidifier's humidistat is accurate after all. Another great product from ThermoPro. I've purchased a couple of different meat thermometers from ThermoPro, and both are outstanding, so I'm not surprised. They're accurate, the display is legible, they have a strong magnet, the design is perfect. The bad news, I have no use for all those junky inaccurate hygrometers. The good news, I finally have good hygrometers, one for the basement, one for my humidor, and one for my living room. I'm all set.

I didn't realize these came three to a pack but I'm glad they are now mine! Works great to monitor temp and humidity on different levels of my home. Batteries were included and it will be beneficial when determining if a humidifier or dehumidifier is needed during different seasons.

These work fine. Easy to read. Not too big and seem accurate enough.

Nice hygrometers. Good price. All 3 read the same and work perfectly. I use one upstairs in the living room, one in the basement and one in the laundry room. If I keep the humidity around 50%, the temp can be 73-78 degrees and the house is still comfortable.

As you can see from my photo, they are VERY consistent with each other. The temperatures indicate within 1 degree of a very accurate thermometer of mine. As for the humidity levels, I have no other hygrometer with which to compare readings. But since they're so consistent, and based on most reviews, I suspect they are accurate, or at least very close.Readability is excellent if there is good DIRECT light on the screens. However, in a not-so-well-lit room the readability falls sharply for my older eyes. Even in a relatively well-lit room, the display isn't so easy to read if it faces away from the light source. There's a convenient push button on the back to go from Centigrade to Fahrenheit, or vice versa. Back there you'll also find a convenient fold-down kickstand, and a plenty-strong magnet to attach the device to steel and/or some magnetic stainless steels.I particularly appreciate that each of these are powered by a common, easy to find, AAA battery. So, I'm able to use my rechargeable Tenergy batteries - also bought here on Amazon. I can't yet comment on how long a rechargeable will last, especially since they are 1.2 volts, not 1.5 like non-rechargeables. But, with a freshly charged one, the display is just as distinct/sharp as with a standard 1.5 volt battery.So, I feel I can honestly recommend these for price, function and convenience. However, long-term reliability still remains to be seen. I will update this listing as time passes to let you know if they are holding up as well as I would hope.

They work . Good price. Very useful to have. At this price, can put in many rooms.
