U20L Water Level Logger Deployment

Onset offers high-accuracy, pressure-based water level data loggers for deployment in depths of up to 250 feet in fresh or saltwater wells, streams, lakes, wetlands and tidal areas. These water level loggers feature research-grade accuracy at a great price, and are extremely easy to use, with no cumbersome vent tubes or desiccants to maintain. Stainless steel, titanium and polypropylene models are available.
