Top 5 Digital Swimming Pool Thermometers

Digital pool thermometers are the best way to tell what the temperature is of your swimming pool. I know it sounds pretty obvious but so you know, not all pool thermometers are the same. In fact there are two different categories of thermometers such as digital and your standard mercury ones. Also for a swimming pool you can have a floating or handheld one.

We would like to recommend you get a nice digital handheld or floating thermometer to read the temperature in your swimming pool. The reason is that mercury filled floating thermometers can get damaged from being in your swimming pool from either the weather or swimmers. The problems with these types is that if they break you could have a real mess on your hands including mercury in the water and broken plastic and glass that could rip the liner or even worse, hurt a swimmer. 

If you do decide to get a floating thermometer then make sure that you tie it to one place in your swimming pool so that it doesn’t just freely float around. Most people like to tie their thermometers to the ladder.

With that said, here are the top 5 digital pool thermometers that we recommend for your swimming pool:
