Ambient Weather WH31PF Wireless Waterproof Floating Pool and Spa Thermometer
8-Channel Wireless Waterproof Floating Pool Thermometer for Ambient Weather Stations. Connects to AmbientWeather.net and is compatible with WS-2902, WS-2000, WS-1965, WS-3000, WS-4000, WS-5000, WS-1938, WeatherHub and ObserverIP Series Weather Stations. The WH31PF is sealed from the factory and includes batteries that last up to 3 years. There is no other maintenance. This sensor is designed to be replaced every 2-3 years.
The WH31PF is waterproof, wireless, and floats on the surface of the water. The sensor communicates with many Ambient Weather Stations (WS-1550-IP, WS-1965, WS-2000, WS-2902B, WS-2902C, WS-3000, WS-4000, WS-5000) via 915 MHz. When used with one of the above-connected weather stations, the WH31PF data can be monitored on AmbientWeather.net, where you can set up text/email alerts for different conditions.
Perfect for ponds, tanks, and any other fluid-based applications.
This sensor has a IPX6/IPX8 waterproof rating.
Important Note: The WH31PF is designed to float. If the WH31PF is used under a cover and the sensor is constantly submerged, the additional pressure will lead to premature failure. Moisture will enter the sensor compartment and cause sensor failure.
If you use a pool or spa cover, we suggest ordering the WH31P probed sensor instead.
