Review on 🌡️ ERAY Digital Psychrometer Thermometer Hygrometer - Backlit Temperature and Humidity Reader Meter with Dew Point and Wet Bulb, Includes 9V Battery by Jose Isaacs

I compared the accuracy of this device to my Kestrel 4500. No, maybe not an entirely fair comparison as Kestrel costs 10x more, but still a useful point left. After several parallel tests, I've found that it takes some time to acclimatize, so you need to leave it in place for a few minutes to get an accurate temperature or humidity reading. If that suits you, then it might be a good price. I'll probably send mine back and look for something that will stabilize and calibrate quicker.
