Stay informed about your pool's temperature with Bestway's digital floating pool thermometer. Featuring a large, backlit LCD temperature display, you can quickly and easily read the temperature in both Celsius and Fahrenheit, whether in sunlight or darkness. This thermometer has a built-in solar-powered battery with a one-touch on/off switch. It automatically turns on and lasts all night, ensuring you always have an accurate temperature reading of your water. The temperature range is from 0-50 °C (32-122 °F), and the thermometer has an IPX7 waterproof rating, making it fully submersible. The floating design and attached string keep the thermometer in place, allowing you to check the temperature before dipping your toes in the water. Made from impact-resistant, shatterproof materials, this thermometer can stay in the pool all season long, regardless of rain or shine.
