The LTC Levelogger Junior logs conductivity, as well as water level and temperature. Like the LT Levelogger Junior Edge, it is easy to transport, program, deploy and retrieve data. It combines a datalogger, 5-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).
The conductivity sensor is a 4-electrode platinum sensor, with auto-ranging capabilities. The minimal maintenance, sealed LTC Levelogger Junior is simple to clean and calibrate, even in the field.
Using Levelogger Series Software, it displays conductivity, temperature, and temperature-compensated water level. Memory is non-volatile and stores up to 16,000 sets of readings. Measurements are linear, in any interval between 5 seconds and 99 hours.
