Review on 🌑️ ThermoPro TP55 Digital Hygrometer & Thermometer: Jumbo Touchscreen, Backlight Monitor by Bim Cook

Revainrating 1 out of 5

Inaccurate humidity reading

The attached images are standard salt tests used to check/calibrate hygrometers. I spent 12 hours on the salt test (google it if you don't know - it's a test where you put salt water and a hygrometer in a ziplock bag). And both show 64 and 60. If you are familiar with the salt test, you will find that a properly working, calibrated hygrometer reads 75% after 12 hours. Those numbers don't even come close, and for some reason this device shows less moisture when it's on its stand.

Pros
  • Easy to read control panel
Cons
  • Something is wrong
