Nice hygrometers at a good price.
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.

Great for assessing humidity and temp
These are easy to use and seem to be pretty accurate. The humidity in our basement was starting to affect the flooring so we wanted a baseline of how humid it was before running the dehumidifier (it was previously too dry) it functions easily and was a great value. It was very responsive as we moved it around, too. It’s not the brightest screen, but it works well.

Accurate Information, small & reliable
This is my second 3-pack purchase of these terrific small thermometers. They are completely reliable and display consistent and accurate indoor temperature and humidity. Also works as a fridge or freezer thermometer.Very versatile to use on a surface with its kickstand, to hang on a wall or to attach to a fridge or similar location via the magnet. Large numbers in the display are easy to read.(Just so you know: No backlighting for night viewing. Not a dealbreaker for me.)One negative: 3 batteries are included in the packaging and every one of them was dead and useless. Be prepared to supply your own fresh AAA for each unit. Battery you install will last long, but the ones supplied probably won’t work at all.The 3-pack of instruments is a very good value. Handy to read metrics for those storage places like the garage, basement or attic. Nice gift for a new homeowner.

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

Easy to read from a distance
Batteries are included and were very easy to install. The gauges worked immediately. I appreciate that the size is small enough not to interfere with furnishings but large enough to read from a distance.

Excellent for monitoring temperature and humidity.
These gadgets are so handy and very accurate. I use them to ensure I don’t have mold issues in my condo or in my houseboat. I have three on my houseboat; one each in the galley, salon and cabin. The three in my condo are one each respectively in my bedrooms and kitchen. My daughter and son-in-law use them in their house and in their cruiser. They are small so you can put them anywhere. I find them to be very accurate in that the temp is consistent with my thermostat and the humidity level is very close. Good quality for the money. Would highly recommend.

I’m Happy! (Pending Long-Term Dependability)
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.

These are the ones you want
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.

All units appear to be accurate and closely calibrated with each other. No issues so far.
Daniel Patterson –
I have purchased these over 10 times and I like them. They are used in a Juice factory.Pros-They appear very accurate.-Battery lasts a decent amount of time.Cons-They are not water proof, and don’t hold up well to high humidity.-Does take several minutes for thermometer to report current temp and humidity. Although. this is expected and not really a large fault.Summary-I recommend.

Very accurate in measuring temperature and humidity, may be set to Fahrenheit or Celsius, with just the push of a button
