Solinst Model 107 TLC (Temperature, Level, Conductivity) Meter

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).

The TLC Meter uses a ‘smart’ conductivity sensor with platinum electrodes to measure conductivity. The conductivity is displayed on the rotating screen along with the associated temperaturemeasurement. The ‘smart probe’ displays conductivity that has been standardized to 25°C, i.e. Specific Conductance (displayed as EC). The conductance temperature coefficient is 2.0% per °C. Calibration is simple, using 1413 μS, 5000 μS, 12,880 μS, and/or 80,000 μS solutions for 1, 2, 3, or 4 point manual conductivity calibrations.

For automated water level, temperature, and conductivity datalogging, Solinst also offers the LTC Levelogger Junior.
