Review on Sper Scientific 736930 Barometer: Accurate Weather Forecasting Device for Precise Measurements by Sean Garrison

I am surprised by other reviews. I'm getting fairly accurate readings compared to online readings from nearby weather stations and am impressed, especially given the accuracy of the labels displayed. The instrument is very light, but I don't see it as such a responsibility that I hang it on the wall and periodically take it off to calibrate. This makes turning the calibration screw a bit more difficult since there is no weight resistance, but you learn that with practice. When you use classic face tapping to determine if the pressure is increasing or decreasing, you need to stabilize it with your other hand. These are minor issues, however, considering the meter's performance and price. Another reviewer also chats about the temperature. It's a barometer, not a thermometer. It doesn't claim to measure temperature, so I'd ignore that review.
