The Levelogger Edge is an absolute (non-vented) water level 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 Levelogger Edge firmware version with the latest Levelogger Software version. See Section 1.3.1.
