Review on 🌑️ Top-rated BestAir HG050-PDQ-4 Hygrometer, Humidistat Humidity Monitor, 4 Pack - Reliable Accuracy and Easy Monitoring, White by Matt Watson

Revainrating 2 out of 5

Useful only for those who don't need or care about accuracy

I have calibrated the one I bought using both the potassium carbonate test and the dew point calibration. The reading is almost 10% higher than the actual humidity. This inaccuracy is so great that even if you ignore the numbers and only use the Low, Best, and High ranges, most of the time you will get incorrect information when the actual humidity is in the Best range.

Pros
  • Hands free operation
Cons
  • Very expensive
