5 Best Digital Pool Thermometers

Digital pool thermometers are the best way to tell what the temperature of your swimming pool is. I know it sounds pretty obvious, but not all pool thermometers are the same. There are two different categories of thermometers: digital and standard mercury ones. And you can have a floating or handheld one.

5 Best Digital Pool Thermometers

Mercury-filled floating thermometers can be damaged from either severe weather or swimmers. If they break, you could have a real mess on your hands, including mercury in the water and broken plastic. Not to mention broken glass that could rip your liner, or worse, hurt a swimmer.

Here are the best 5 digital pool thermometers that I recommend.
