TempPro TP49 3 Pack Digital Hygrometer Indoor Thermometer | Humidity Meter Mini Hygrometer with Temperature and Humidity Monitor Outdoor and Room Thermometer Weather Station

Big easy to read numbers. Well made. Seems to be accurate and reliable. Inexpensive enough to have several in multiple locations you need to know the temp and humidity. I place them in storage containers where I need to control the humidity.

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. UPDATE: I've had these for over 2 years now, and they continue to work perfectly - even out in my hot, or cold, or hot and humid open-air sunroom! It turns out that 1.2-volt Tenergy rechargeable batteries keep each unit working great for a few months at a time before needing recharging. But be aware that the display all but disappears if it's kept in a freezing cold place, like my sunroom in winter.

I was pleasantly surprised how well these worked despite the low price. They came calibrated and with batteries. Thermometers show temp (F or C) and humidity and work anywhere.

As suggested, I put them all 4 right together in one space, and they never said the same thing. The offices are cooler than the main room where most of us sit, and we needed a neutral way to settle the arguments about the thermostat. These are all within a degree of each other, but the lowest and highest are a full degree different. But I'm hoping they'll be close enough to correct that they'll show our thermostats are wrong! They all worked, and I love the AAA battery, and not the little round watch batteries.

I am extremely satisfied with this product. Very no frills, just provides temperature and humidity, and for me that was all I needed. I have one in my office at work, while the remaining two are in various rooms in my house. Uses 2 AAA batteries that are supplied. With both a built in stand, and magnet you have easy display options. For me this was the perfect solution.

Very accurate, small and compact, and I love that it also tells me the humidity. Great product for a good price!

Works well and easy to read. Using them to see how well A/C works in new home.

I had to buy a small under-the-counter refrigerator because my apartment's refrigerator no longer worked - temp in the refrigeration compartment regularly reached 60 degrees. I wanted to be sure the temp in my small refrigerator remained consistent so purchased the tiny temp/humidity indicators. They work great, the fridge also works great and now I can keep my milk and other perishables at the correct temperature! 3 in the pack so I also use them to monitor the temp in various rooms in my apartment - large digital display is easy to read at a distance. There's also a magnet on the back in the event you want to attach it to the outside of a refrigerator, etc.

These hygrometers work great! I have them placed throughout my house to monitor the temperature and humidity in different rooms. The displays are clear and easy to read at a glance, and they provide consistent, reliable readings. They're compact, easy to set up, and perfect for keeping an eye on indoor conditions. The three-pack is a great value since I can monitor multiple areas of my home. I'm very happy with this purchase and would definitely recommend them.

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.

We had one older one to help monitor temperature and humidity in our garage gym and have ordered this 3 pack since having a baby and wanting to monitor stroller and room conditions more closely. We find them very accurate and I believe the brand is a great link between quality and affordability which definitely helps with our trust in them.
