I live in an area that has extremely cold temperatures in the winterwill outdoor thermometers work for me?
Yes, some of the dial thermometers will record temperatures down to -20° or -30° F. Some of the digital thermometers with outdoor sensors can record temperatures down to -40° F. Normal alkaline batteries will lose power in cold temperatures and will freeze and stop working in freezing temperatures. When the temperature goes back above freezing, the batteries will thaw and start working again. This will not harm your temperature sensor. However, lithium and titanium batteries will function at extremly low temperatures. So, if you are expecting temperatures to drop below freezing, it is best to replace your alkaline batteries with lithium or titanium batteries. They are available at most electronic or camera stores.
