Review on 🌡️ Advanced Extech Digital Thermometer: Accurate Temperature Readings with Ease by Alex Tilden

Bought because I already had Extech and Extech 445580 calibration pots, both of which were positive purchases. As with 445580, it is not calibrated. Ironically, the humidity calibration screw on the back seemed to have a dubious effect. While the temperature calibration screw definitely worked, the humidity screw didn't really seem to do anything, even after being twisted and twisted waaaaaa more than the manual says. Like it's just for show. He's currently working as a controller in a client's salami drying room and I don't trust him. It's currently roughly equivalent to a freshly calibrated 445580 if I get both to normalize side by side under perfectly stable conditions, but it took me hours of fumbling to get it right. I want to buy something else.
