Records water level and temperature in depths from 4m to 76m<\/strong>; narrow range provides best accuracy in shallow waters. Available in stainless-steel for shallow wells, streams, lakes, and freshwater wetlands and in titanium for saltwater\/brackish wetlands and tidal areas.<\/p>\n The HOBO U20 Water Level Logger is used for monitoring changing water levels in a\u00a0wide range of applications including streams, lakes, wetlands, tidal areas, and\u00a0groundwater. The loggers are typically deployed in existing wells or stilling wells\u00a0installed specifically for deploying the loggers.

The HOBO Water Level Titanium is recommended for saltwater deployment for recording water levels and temperatures in wetlands and tidal areas. The logger uses precision electronics to measure absolute pressure and temperature and has enough memory to record over 21,700 combined pressure and temperature measurements.<\/p>\n Requires HOBOware Pro software and either a U-DTW-1 Waterproof Shuttle or the Base-U-4 Optic USB Base Station for configuration and data offload.
