The LTC Levelogger Edge logs conductivity, water level and temperature. It combines a datalogger, 8-year battery, Hastelloy® pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 7/8" x 7.5" (22 mm x 190 mm). A Titanium ceramic PVD coating protects the body against corrosion. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal maintenance, sealed LTC Levelogger Edge is simple to clean and calibrate, even in the field. Using Levelogger Series Software, it displays conductivity, temperature, and temperaturecompensated water level.
