ACCURATE READINGS - The pool thermometer has a clear LCD screen with optional 12/24 hour time display, providing accurate readings in Fahrenheit and Celsius. The temperature detection range of the water tank sensor is -40°F to +70°F (-40°C to +158°F), and the temperature detection range of the indoor host is -9.9°F to +50°C (14.2°F~122°F). Record the minimum and maximum temperature values. Wireless Connection - Wireless Range: 433MHz/100m. The WiFi wireless pool thermometer has a one-way connection, allowing you to use the receiver to check temperature readings without leaving the room.
