The ThermoPro TP50 is a simple indoor thermometer and humidity gauge that works well for checking room conditions, especially in basements or other spots around the house. It has a magnetic back, tabletop stand, and high and low memory, and the battery life has been described as lasting for years. The humidity reading is especially useful for tracking comfort and asthma triggers. The main caveat is durability, since the temperature display has failed after about a year in one case, and some prefer Govee models for accuracy.

  • The hygrometer can help compare indoor humidity readings against a thermostat across different rooms.

  • The humidity gauge can be useful for monitoring indoor conditions, including for asthma-related needs.

  • The device can support long-term use with battery life lasting for years in reported use.

  • The unit can be used in multiple locations around the house for humidity and temperature monitoring.

  • Temperature functionality can stop working while humidity continues operating.

  • The device can stop working after about a year of use.

  • Accuracy expectations may be lower than competing hygrometers, with Govee models reportedly seeming more accurate.

  • Prime-exclusive pricing can be confusing, since some buyers report not seeing the coupon or deal math on the page.

All I want is temperature. Other numbers mean little.

I have had mine for about 8 years or so. Name on it was Thermpro then. Humidity gauge is a good tool to have especially for asthmatics. Battery last for years. Good buy.

I've 5 of them around the house, 4 indoor, 1 outdoor and I am able to see on the app with historical temp. I bought a package of 3 back in Sep of 2023 for $23 so the current price is not bad.

Thermo Pro? Or TEMP PRO? Mistakes? Or purposely mislabeled?

TEMP Pro. Not THERMO Pro. I think this guy is pretending it's a typo or an honest mistake when it's happened four times
