Review on 🌡️ EXTECH Instruments Digit Thermometer: Accurate Temperature Measurement for All Applications by Greg Moore

I've had it for 2 1/2 years. At first it seemed to compare well with the other two humidity sensors I had. Humidity readings have decreased over time and are now approximately 15% lower than other sensors. As other reviewers have reported, the humidity calibration screw doesn't work, unlike the temperature calibration screw, which works fine. So I'm going to support another reviewer's suggestion that you should check the calibration work when purchasing. Screw right away instead of waiting until you need it. (For me, those screws were covered with small foam pads that I had to peel off. Don't make the mistake of "adjusting" the adjacent Phillips head screws that hold the case together.) I expected more from Extech. .
