Bộ ghi dữ liệu mực nước ngọt (13ft) - HOBO U20-001-04

Overview

Monitor water levels and temperatures in wells, streams, lakes and wetlands (freshwater) with this 13-foot HOBO Water Level Data Logger. With its narrow range this logger provides the best accuracy in shallow waters. This logger offers a great value and easy deployment since there are no cumbersome vent tubes or desiccants to maintain. For saltwater deployments, such as brackish wetlands and tidal areas, see HOBO U20 Water Level Titanium.
