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

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.

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.

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.

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

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.

Having a hygrometer is important for maintaining a healthy living and/or working environment, for protecting the space itself (e.g., wooden floors, wooden surfaces, etc.), and in some cases, for protecting objects that are particularly sensitive to humidity levels (e.g., wooden musical instruments). In our case, we needed all three. After getting tired of dealing with an overpriced and completely inaccurate Extech thermometer-hygrometer (yes, one of those that theoretically can be calibrated with special salts that are equally expensive, which did not work in our case), we decided to try the inexpensive TP49 from ThermoPro. Given the very good price for buying three instead of one, we preferred the three-pack, which is also the easiest way to check their accuracy. Our reasoning was that if they show the same readings (within the manufacturer's deviation limits), it's almost certain that they are accurate, while if they show different readings, then you probably can't trust them. And bingo, when they are in the same room, they all give very similar readings, and so we have the accuracy we need (as much as is needed for normal household use, not laboratory-level accuracy for chemistry or manufacturing). By having three, we also have a very easy way to verify from time to time that they remain accurate. Another big plus: in the past, we needed warranty support from ThermoPro for a cooking thermometer that had a problem, and the handling and resolution of the issue were as good as it gets. For all the above reasons, I highly recommend the three-pack of TP49s, both for the thermometer function (which is the easy part) and for the much more technically demanding (see accuracy) hygrometer function.

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.
