The miniTROLL Level - Temperature - Data Logging unit is the leading instrument for water monitoring. Powerful, dependable, versatile, easy-to-use and small. Just place it in the water and have it collect data. The miniTROLL can be found monitoring water levels in thousands of rivers, lakes and wells around the world and is counted on by professionals and governmental agenices to provide highly accurate data. With up to 1MB of non-volatile memory (220,000 readings) and the smallest diameter in the industry, the miniTROLL is ideal for both long and short-term groundwater monitoring applications.
