The Levelogger Edge is an absolute (non-vented) datalogger, which measures groundwater and surface water levels and temperature. Water levels are displayed as temperature compensated pressure readings, and can be barometrically compensated with the aid of a Barologger Edge.


Solinst recommends using the most recent firmware, Version 3.003, when using a Levelogger Edge with Software Version 4.2.
