Water Level Loggers


The OTT CTD is an integrated sensor and data logger for measurement of water level, temperature, and conductivity in groundwater and surface water applications.
It features a robust ceramic measuring cell for long term accuracy and has outputs for salinity and total dissolved solids (TDS).  Its built in datalogger manages and stores all measurements at user-programmable intervals.
