73 reviews for ThermoPro TP49BW Digital Indoor Hygrometer Thermometer Humidity Monitor

  1. Amazon Customer

    I love these little thermometers, I wish I’d have bought more. There are two in the package, comes with batteries, uses one AAA. They seem to be accurate, they read identically in the same environment. I can’t tell about battery life since I just got them. They have a small magnet on the back so you can attach them to the refrigerator or any other metal surface. Reads both temperature (C/F) and humidity. Handy to have.

  2. Richard Valles

    Works as advertised, standard battery (nothing special) clear and generous display. Seems accurate and according to the literature the battery should last approx. a year. I like the magnetic back.

  3. R. Dirienzo

    I have a bedroom that is colder than the rest of the apartment and the living room gets more sun than the rest of the rooms, so it’s nice to know the temp in those rooms, since the thermostat for the apartment doesn’t show the temp accurately for those rooms

  4. Amazon Customer

    I have 3 of these. One for Home. One for Office. And one lives in my carry-on. I like to know the exact temperature and humidity everywhere!! Super Accurate for weather geeks like me. First Battery still works from 2 years and going strong. This is a 5 star product.

  5. Rickster1

    Small footprint, simple, easy-to-read, accurate. What more can I say?

  6. Rayme

    Works as advertised!

  7. James McCanna

    As expected.

  8. Chronepsis

    Temperature and humidity level readings seem to be fairly accurate when compared to other devices I have

  9. Brenda Alvarado

    Im a Lash tech so this has become an essential.

  10. White Rabbit

    I have four other thermometers and two other hygrometers. When I put this unit side by side with the others, this hygrometer is within 2-4% of the other ones. The thermometer, however, consistently reads at least 10 degrees cooler than the other 4 thermometers. Fortunately I bought this because I am interested in keeping the humidity of my rooms within a certain range, so I am mostly interested in the hygrometer readings. The thermometer is not that important to me; I know when it’s too hot or too cold in my room. For the price, I got a decent hygrometer.Amended review: the seller quickly reached out to me about my problem with the thermometer and offered to help me resolve the issue. I quickly received a new device and it is working perfectly. For that reason I am upgrading to 5-star. Reliable trustworthy seller.

  11. Esteban

    These hygrometers are okay. Can’t go wrong with the price. The magnet from one of the ones I got kept falling off until I pressed it in really hard. Might have to add some more adhesive. Other than that, they do their purpose and are about 1 degree off from each other.

  12. ParaboTECH

    These digital thermometers come in handy for many purposes. I use them to verify the temperature differences between rooms in the house. I also use them for computer server rooms and racks. They are not the most accurate devices, but for the price, they are good enough. I have several located side by side and they display within 1 or 2 degrees and within about 5% humidity of each other. The style is nice and simple, and unobtrusive. Battery life is about average. I would recommend these for general indoor use.

  13. Foster

    It tells the temp pretty decent I suppose

  14. CM Wong

    Great to know the temperature and humidity at a quick glance. Stands upright.

  15. itsme

    Was having issues with air conditioner thermostat. Was told it is just fine. I purchased the product to check the accuracy…by putting them in different parts of the house I got the correct indoor temperature.

  16. M. L. Stierheim

    It is exactly as picture and exactly what I was looking for in those peripheral rooms that vary more in temperature.

  17. M. Ward

    Works wonderfully! We wanted to know temperature for different rooms in our house. This little gadget is portable, quick, and can be either F or C degrees. The temperature reading is accurate based on two other thermometers in the house (that are not movable). It is also helpful to see the humidity reading–not sure how accurate the humidity reading is, but definitely it gets us in the ballpark–we can see if we are in the “comfort zone” and if humidity is going up or down. If you do not need other bells and whistles, this may be just what you are looking for. Call it the flip phone of thermometers: if you just want to make a call, you don’t need fancy color displays, cameras, texting, ability to watch movies, gaming, etc. That’s all we were looking for, just a simple answer to the question what is the temperature in this room? We like it so much we are getting two more, so we will have 1 in an air-conditioned room, 1 in non-air-conditioned space, and 1 in partially finished basement.

  18. Ben

    Got these to use in a reptile tank. One for the cool side, one for the warm side. They seem accurate, the temp difference is what I set the heat mats at, and the humidity goes up when I use the fogger.Easy to use, like that it has F and C options, and can be held up by a magnet, or be set up on the “easel” bar.

  19. Michelle

    These inexpensive thermometers are perfect to place throughout the house. When I claim “I’m hot”, and the spousal unit disagrees, I have empirical evidence to support my claim.

  20. MR

    Use these in a large travel trailer. Very accurate and now know when I need to turn on or off the dehumidifiers. I have their kitchen thermometer which is also great quality. And nice batteries are included.

  21. RhondaB

    Our grandson’s room is never the temperature of the house. We couldn’t tell if he was getting cold or too hot when he slept. After getting this device, we were able to adjust the temp with the ceiling fan and our A/C/ furnace to make sure he was comfortable. He sleeps very sound now. Battery is still going strong after 6 months.

  22. J. Review

    Used inside when our AC went out- to know our home temp. Works well. It could be a little larger.

  23. ~*Ashley*~

    Not only dose this little guy let me how how hot or cold my upstairs is to my down. This little guy let’s me know if I need to add monster or take it away to keep it peaceful in my house. This ensures no unwanted allergy attacks or migraines.

  24. M Keppel

    small enought for my cigar humidor, gives an accurate reading of temp and humidity %. I took it outside and matched it to the current weather humidity reading and it matched. 2×2 inch wide and 1/2 inch thick.

  25. Miss Deb

    I actually thought this would be a little bigger, but for the size, is still easy to read from about 5ft or so (I am older, eyes and hearing shot) Don’t know about ‘battery life”.. but I would assume that is more about the quality of the batteries, not the product!

  26. Blue Bonnet

    Works great

  27. Speedster

    Purchased in Feb 2022 and they are still running on their original batteries. The humidity & temp readings seem to be consistent with each other and with other temp/humidity monitors, and with the humidity readings of our dehumidifiers. Would definitely buy again.

  28. Sherri

    Has a little, very strong magnet on the back. You can also stand it up like a picture or hang it. I have bought 3 and back to get more. Use at work, in my car, in different rooms of my home and garage. Love it. And it shows humidity! Can’t beat it.

  29. nobis87

    Works as should

  30. Love the oldies

    These 2 units match up exactlly with my vintage barometers TAYLOR and SWIFT.

  31. Paul Jarnot

    If you are not overly concerned with accuracy or the humidity readings it is ok, reads close but give or take at least 5%

  32. Christy

    The numbers on the display are nice and large. It seems accurate. I don’t have another one to compare it with. I really like it though, and would definitely buy again.

  33. B Shull

    Love the Thermopro Brand, bought for the Hygrometer and the temperature setting was a Bonus. Would Buy Again.

  34. acelera su

    I recommend this product. I had one this is my second one for another section of my house

  35. Tex

    Thia is my second purchase … the first still working fine in model train room. This one is going into the master walk in closet.

  36. judy chubirka

    I need to keep my parrots room warm. So it let me know when I need to turn on their heater.

  37. Laura Zebrowski

    I own 3 for each floor of my home. It helps me know temperature in my living room since thermostat is only analog and not accurate.

  38. sripada

    It’s use very fullI used it in warehouse for accurate temp

  39. Terry Thorspecken

    I put it in my barn and outer buildings. Small so doesn’t take up space or get in the way.

  40. Kindle Customer

    This is a quick and easy to read device. But the magnet is not strong enough to hold it up, I had to reinforce it with another, stronger magnet.

  41. Z. Jin

    Large font and easy to read. Not sure how accurate they are though. But roughly fine.

  42. LWcatmom

    A little smaller than I thought it would be but perfect anyway. Using in my horse tack shed to make sure medicine stored there doesn’t get too hot. I would definitely buy again.

  43. Kyle M.

    I like it. It’s easy to read. There is a five percent difference between my dehumidifier and the device. That said, it does give me an indication about my the dampness in my basement.

  44. Stephani Martinez

    This digital thermometer is very functional and meets the needs I need it for.

  45. UptownGirl

    Now how is that headline, for a positive endorsement of this product?I knew from day one this was a keeper (and winner), so I immediately bought a 2nd one for lower level of my home, with the bedrooms and bathroom.I love the “easy” and included AAA battery (hate those coin type batteries); with AAA’s, you can buy them anywhere, and they’re easy to insert :-)It seems very accurate, based on a built-in thermostat/thermometer in my master bedroom. The temps always match.This product has also been very helpful as to where or when I decide to run my portable dehumidifier – either upper or lower level. And if I’m being honest, this is the real reason I purchased, to check the humidity levels of my home (but the temperature of room is nice to see at a glance too.)NOTE: If I wanted to make a suggestion to the manufacturer, maybe provide a button on the front so we can light up the viewing panel anytime. When the room or area of room becomes dark later in the day or night, it’s impossible to see the reading without moving it toward light – but this wasn’t enough to knock down my 5-star rating. It would be nice to have a backlit button, though. I’d gladly pay a bit more.

  46. Beau Schommer

    Seems to work correctly

  47. MsScarlet

    These little hygrometers are perfect for my needs of measuring humidity in my house. I live in a very humid area and try to keep an eye on and manage the humidity in our bedrooms particularly. I had one of these in the bathroom as well at one point, and I believe, like other reviewers have said, that when exposed to very high humidity, these will begin to malfunction. Otherwise, I find the display normally easy to read and it’s easy to place these anywhere in the house. 1 AA lasts a long time in these as well. I would buy again despite one malfunctioning, good little devices for the price.

  48. Bd

    Works as sould

  49. bobfishaz

    Bought these to use in my wine cooler, I placed both side by side to see if i would get the same readings. Here’s what i got. Temp display was 2 degree’s off from one another and the humidity reading was off by 1 point. Not bad, but i think there quality control can be better. I’m pretty happy at least what i’m using them for. I recommend, but, i don’t highly recommend, depending what your using them for. Easy to read, like they update approx. every 8 seconds, accuracy is off a little, battery life has been good so far. Stand collapses into unit that works good.

  50. WCogs

    Works fine.

  51. Janice K. Anderson

    The unit came on time and was operational right out of the box. Cross checked the accuracy with a ‘k’ thermocouple and a lab thermometer for variance. The unit was within specs and maintained acceptable percentages throughout the scale. Very pleased with the THERMOPRO TP49 device.

  52. Ramona A. Huffman

    Inside humidity. Very small though!

  53. Innocenti

    as advertised, works for me!

  54. MaryC

    The bedroom gets very dry in the winter time and I need the humidity to be at a certain level for sleeping and use of a CPAP machine. This thermometer has provided just the information that I need to set my humidifier at the right setting needed.

  55. JArguello

    I used these in the rooms we most frequent to determine if the heating and air conditioning is being distributed equally.

  56. Mario Lewis

    It performs the functions needed but its so small you’d have to keep it close because it might disappear.

  57. Jeff C

    I’ve compares this against two other devices (one analog) and it’s accurate down to the percent humidity wise. As for temperature, it’s sometimes a half a degree off which is not a big deal. Which shocked me the most was the size even though they listed the measurements. These are small yet offer a large clear image of the temp and humidity. I also apparently don’t read descriptions well because I didn’t realize this had a built-in magnet, which was amazing because I now have it attached to my pole in the basement for easier reading. Couldn’t be happier with this purchase, especially for the cost!

  58. Ruth C.

    This thermometer is small enough to fit in the palm of my hand, so it’s easy to carry around. (It’s probably also easy to lose, but so far I haven’t!) It was super easy to set up — just put in the battery and it immediately starts working. On the back (top area, on the right) there’s a tiny button that you push to choose either Fahrenheit or Celsius. Very affordable. As far as I can tell, it seems to be accurate. I would absolutely tell my friends to give it a try.

  59. Rick F

    We use this to check the true temperature in our park clubhouse because the thermostat is not in the main room but in the adjacent hallway

  60. Russell

    This is perfect for my office. We’ve had lots of issues with hot and cold spots in our large office. Maintenance always says ‘It’s set for 72 – should be fine.” But since this responds so quickly to changes, I can move it from one side of the office to the other and show how one person is sitting in Hawaii while the other is in Anchorage.Heck, at this price, I’m thinking of getting a few more so we can ‘map’ the temperate zones in the office. Since everyone shares desk (we’re 24/7) it may help new folks choose the best seat in the house.

  61. Missy v.

    I’ve been using it for 6+ months with no issues or battery changes. Small, compact and gives you basic temperature and humidity reading.

  62. Ingrid Peterson

    No more squinting to read my mercury thermometer. This digital thermometer records the same temperatures, so must be accurate. I like the humidity reading, too, and that there are no other numbers cluttering up the screen.I also love the versatility of using the stand or the magnet.

  63. Pete

    The product seems to be put together pretty well…Has a nice weight behind it. I purchased this alongside a Levoit humidifier to measure different areas of a room for the humidity levels (monitoring for plants). Placed this right next to the Levoit, and it went lock-step with the humidifier…whenever the Levoit readout changed, so did this device…Validated both of them. A small button on the back of the device changes the readout from C to F. Temperature aligns with my thermostat as well. Couldn’t be more pleased with the purchase.

  64. Bob from Dallas

    Accurate and easy to read

  65. J. M. Hardin

    After moving into a new house last fall, I hadn’t realized how hot my new place is. I needed to get a thermometer to see just how hot the living room gets, and this one is perfect. I wish I had gotten an indoor/outdoor thermometer, but this one’s perfect for the job. The fact that it can track the humidity as well is a huge bonus for the price.

  66. Nacash

    It works as soon as you enter the batteries and I believe it comes with the batteries !

  67. Larry

    These are very cute little Thermometers. They were smaller than I expected, but I did not look at the dimensions, so that’s on me. The stand folds out nicely and is easy to read.

  68. Toby

    A little difficult to set up, but great after that.

  69. Stefan H.

    Purchased 2. They are within 0.3 degrees F of each other and reasonably accurate compared with another thermometer I have. Humidity shows the same value on both. They come with a magnet on the back. (Ideal to stick one thermometer on an air conditioner air supply grill and one on the air return grill to keep an eye on the AC performance. The air temp. diff. for a well functioning AC should be between 16 to 22 deg.)

  70. Noe olvera

    Good

  71. Tres Texas

    The temperature part of this device appears to be accurate. The relative humidity reads a lower value than the actual humidity in the house. I bought the 2 pack and both units have same issue.For the price I guess you can’t expect scientific accurancy

  72. Clark Blome

    I find an indoor thermometer with the quick and varied weather. This one is no trouble to read !

  73. Stephen C. Barnes

    The temperature numbers are accurate
