  1. Kyle

    I have four separate therm pro thermometers all in different places and locations, most common reading is 66.6 the majority of the time…. 🤷🏻‍♂️

  2. Rachel Blythe

    I had a ThermoPro for over a year, but it stopped being accurate. Contacted company and was told they would send me a replacement, which they did within 4 days. So pleased with the customer service. Many companies just don’t bother.

  3. Nick Simms

    Very simple to use and great value for money. Thermo Pro are a good company to deal with. thank you

  4. Angela

    I purchased mine from Amazon and use it 24/7 in my pet hedgehog’s enclosure. I love that it logs the high and low of the past 24 hours so that I can keep tabs of what is occurring in her enclosure. Customer service is also great. I had an issue with the display just less than 2 years from the purchase date, and they offered to send a replacement promptly. This company really stands behind their products!

  5. Frank Orza (verified owner)

    Excellent. Very satisfied. Only hiccup was I was billed twice.

  6. Clay (verified owner)

    I bought to monitor my humidity and it has worked perfectly . Get to see the high and current temps to make sure my VAC is working properly so i’m buying another for the attic to see what is going on up there .

  7. Dennis (verified owner)

    Works good, reasonable priced, good quality product that’s easy to read and understand. It’s accurate when compared to my home’s thermostat’s temperature settings. Fast shipping and excellent customer service.

  8. Jesse

    I’m very happy with this thermometer. I bought two of these for my home. They are accurate, and the battery lost very long, almost 3months now.

  9. Waldo Lamax

    Wow that is such a great product, so easy to use and so accurate, I’m a very happy customer ?

  10. Jackqueline Desaulniers

    I ordered this thermometer to use at work. I really like the displayed info. I especially like the min and max readings as they are useful to show what’s been happening in the part of the office I sit in. It’s very easy to use and doesn’t require set up when I take the battery out.

  11. Kristin Shikuma

    Using it in my Music Room to make sure it doesn’t get to hot in the summer and damage things.

  12. Rodolfo Horstead

    I have a huge bathroom with a very wide floor to ceiling glass block window facing south where I keep most of my houseplants on large open shelf units – plants everywhere. This low profile little unit constantly gives me a very accurate reading of the temperature and humidity level. It also tells you the highest and lowest of each that it has been so far in the room. I depend on it heavily and it has never let me down. For instance – if I take a very warm shower with the door closed – the humidity usually goes up about 10%. After the door is wide open – you can watch the level slowly go down. And the temp is usually right on. You can use it anywhere in the house to keep a check on temp and humidity for whatever purpose. One of the best buys I have ever made.

  13. Jenelle Tingen

    I got this thermometer to see the temp in my trailer, and it serves the purpose. I kind of like the fact that it has a magnet back so I can get it up and out of the way. It’s a simple device, nothing fancy, but it helps.

  14. grfu (store manager)

    I bought three of these monitors (2 for gun safes, 1 for wine room) and they are all working well. They were simple to set up and use, but the company also provides instructions (including an online video). Shipping was prompt and customer follow-up is excellent. If I run into a problem down the road, I’ll revise my review, but I’m happy now. Well worth the price.

  15. Dorsey Battiest

    Works perfect. good deal price and quality

  16. Columbus Thixton

    Super cheap and seems to work well. Compared it thermostat and they both read the same temperature. Love the magnetic mount since I have it hanging on a metal board. Temp seems slightly slow to update but it gets the job done

  17. Alden Linza

    Satisfactory product.A similar but different brand of thermometer/humidity meter has been tried before, and the result is an inaccurate Celsius thermometer with internal conversion.

  18. Carly Dufrane

    “It looks good,” smiley said. “it only happens when the humidity is above a certain point, but I am not sure.”We bought for our newborn so we could monitor the temperature more locally. Arrived on time and very appropriately priced. I would recommend if you want something inexpensive that "does the job".

  19. Larry Fantauzzi

    This device is very useful for those rooms away from the air-conditioning thermostat.It also keeps your room moist, which is important for people with respiratory problems.

  20. Edie Levett

    This is the perfect product for maintaining temperature and humidity, especially for newborns.Lightweight, very accurate, portable, with a battery and a very low price!Four months later, I can still say It is good, and very good.recommended. You will not be disappointed.

  21. Marco Orso

    Perfect work

  22. Charis Noboa

    It looks amazing and it works

  23. Ernie Boldue

  24. Monnie Miron

  27. Reynaldo Jennie


  28. Cayla Ioele

    Great hygrometer, very recommended

  29. Zachery Weck

    I need this as my basement check for humidity and its size enough to connect easily to the wall.

  30. Millie Sklar

    Works well and as advertised. Fast shipping A

  31. Bobbie Cuddihee

    I bought a ThermoPro TP50 digital hygrometer to determine the humidity in my bedroom.I like it to be about 2.5 inches by 3 inches, because it does not take much space on my dresser. It started working upon inserting the accompanying battery. I have had no problems withit. The hygrometer arrived on time in good condition. I have owned it for about 4 months now. To me, the humidity readings seem to be in the ballpark. I cannot attest to degree of accuracy as I have nothing else to measure humidity. The thermometer seems to be correct as the bedrooms temperature is always one degree below my thermostats reading. That makes sense as the bedroom is at the opposite end of the house from the furnace. All to say, I am happy with the purchase.

  32. Tona Barette

    Simple setup.I like it to include batteries.Unlike the akrette brand I bought last year, It is more expensive without batteries.

  33. Federico Emory

    It is a little bit small, but it works very well

  34. Clare Thraen

    Would you recommend it to a friend

  35. Wilford Breiter

  37. Hector Tags

    Great product!I loved it. I bought two!Great work.It is like advertising.

  38. Tia Mellas

    It is easily to set up.

  39. Sebastian Languell

    I really like the accuracy of 0.1 degrees Fahrenheit, although it might be a bit too much.(0.2c is enough!)Humidity and temperature readings also seem accurate.The price of this is about the same as the price of any other worse unitprecision or accuracy.I liked it so much, I bought 5 of them: one for each of our 3 bedrooms and for my wifes and my offices at work.

  40. Lanora Pettes

    Good quality

  48. Keena Weissenborn

  49. Waylon Zaro

    This unit works perfectly!!Read the following horror stories about other portable thermostats.I ordered two other thermostats, one with the wrong temperature, and the second with the wrong temperature, which is 10 degrees too high.

  50. Lynn Karroach

    The price of a good product.Let us know that when humidity drops, you need to humidify your guitar (or whatever it is you are tracking humidity for

    The thermostat is now working.There was a problem with honeywells server.I did not know there was a problem, so when I could not make it work, I was frustrated.It would be great if honeywell could communicate with those customersproblems that the problem was with Honeywell and not their thermostat.

    Fast delivery, project description

  86. Jonna Osbeck

    Compact, useful, accurate.I bought two and left them in my bedroom for two days with two more expensive and probably more accurate thermometers/hygrometers. They all displayed the same temperature and humidity. A rough test, but good enough for me.

  87. Anthony Wilhoite

    That is the kind of expensive product we are looking for

    A convenient, one-week interior thermometer is expensive.Prefer high/low temperature reports.

  101. Curt Mcandrews

    Big screen and very clear reading.Absolutely recommended.

  102. Launa Lavecchia

    We bought two of these for different room, one did not work, did not show the exact figures, so we got in touch with the seller, It is easy to cooperation, then send us another, the effect is very good. We relied on these a lot in the winter to have a general idea of the humidity so we could use our humidifier appropriately.

  103. Ariel Mahon

Question: Any way to calibrate temperature?

Answer: No, there is no way to calibrate this unit. If it is far enough off compared to a proven thermometer or hygrometer that it requires calibration to fall within the manufacturer’s stated percentage of accuracy then it is defective.

Question: Is it display also Date and time?

Answer: No it does not.

Question: Can i reset the comfort range? 79 degrees f is much too high to be comfortable imo?

Answer: The comfort indicator will only apply to HUMIDITY not temperature. 30-80% is typically seen as a comfortable range for humidity. Temperature comfort will vary between individuals, humidity typically does not.

Question: can this be used in a hermit crab habitat?

Answer: I think you should be able to put it in there without any issues!

Question: Will this malfunction in high humidity? i want to use this in a brazilian rainbow boa terrarium and condensation is typical?

Answer: The location I am monitoring typically runs about 75 – 85%. The other day, I discovered a water leak when I put the monitor in a new location. A couple of hours later, it was in a puddle with water drops all over it. Today it seems to be working just as it always has. So, I would say it seems to work well in high humidity.
