1.1.9 LTC Levelogger Edge
The LTC Levelogger Edge provides an accurate and convenient method to measure water level, temperature
and conductivity all in one probe.
Note: Solinst recommends using the most recent LTC Levelogger Edge firmware version with the latest Levelogger
Software version. See Section 2.3.
