The Levelogger 5 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 5.
Note:
Solinst recommends using the most recent Levelogger 5 firmware version with the latest Levelogger Software version. See Section 2.3.

Note:
The Model number refers to the depth of submergence below water level that the pressure sensor can withstand. i.e.: The Levelogger 5, which is available in M5, M10, M20, M30, M100, and M200 ranges has actual water level ranges of 5 m (16.40 ft), 10 m (32.80 ft), 20 m (65.60 ft), 30 m (98.40 ft), 100 m (328.0 ft), and 200 m (656.2 ft), respectively.
