Solinst® TLC Meter Model 107

Temperature, Level, Conductivity

The TLC Meter is ideal for profiling conductivity and temperature in wells and open water. It displays accurate measurements of conductivity and temperature on a convenient LCD display that rotates for ease of reading.

Conductivity measurements are read from 0-80,000 μS/cm with readings giving accuracy of 5% of reading or 100 μS (which ever is greater).

Water level and probe depth measurements are read off the Solinst durable PVDF flat tape, which is accurately laser marked every 1/100 ft or each millimeter. Tape lengths are now available up to 1000 ft (300 m).

For automated water level, temperature, and conductivity datalogging, Solinst also offers the LTC Levelogger Junior. See Model 3001 LTC Levelogger Junior Data Sheet).
