Model 107 TLC Meter (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.
Conductivity measurements are read from 0 to 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 each millimeter or every 1/100 ft. Tape lengths are available up to 300 m (1000 ft).
For automated water level, temperature, and conductivity datalogging, Solinst also offers the Levelogger 5 LTC. (See Model 3001 Levelogger 5 LTC Data Sheet)
TLC Meter Reels
TLC Meter reels are ergonomically designed for ease of use. The reels feature a stand-alone design, convenient carrying handle, and sturdy probe holder. They are robust and smooth running. The battery is housed in a convenient drawer in the front of the reel, allowing quick replacement. The reels are equipped with a a loud buzzer and light, LCD display, menu button, brake and a tape guide stored on the frame.

Rugged PVDF Flat Tape
The high quality PVDF flat tape reels smoothly, remains flexible and hangs straight in the well, regardless of temperature. The flat tape is mounted on a sturdy, wellbalanced Solinst reel. Permanent laser markings each 1/100 ft or millimeter allow accurate readings.
Stranded stainless steel conductors and copper coated steel conductors resist corrosion, provide strength and are non-stretch. They make the tape easy to repair and splice. The dog-bone design reduces adherence to wet surfaces.

Length Options
Solinst Model 107 TLC Meters are available on reels in the following standard lengths:
| Small Reel | 100 ft. 30 m | Medium Reel | 500 ft. 150 m |
| 200 ft. 60 m | 750 ft. 250 m | ||

TLC Probe
The 3/4" diameter (19 mm) TLC Probe is submersible the full length of the tape. The tape seal plug design allows the probe to be quickly and easily replaced, if required.
Size: 3/4" dia. (19 mm)
Weight: 3.5 ounces (98 g)
Water Conductivity Measurements
The TLC Meter uses a 'smart' conductivity sensor with platinum electrodes to measure conductivity. The conductivity is displayed on the screen along with the associated temperature measurement. 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.
The full conductivity range 0 to 80,000 uS/cm and the calibrated range is 500 to 80,000 uS/cm. 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.
Since conductivity measurements are temperature sensitive, a short wait of 20 seconds per degree Celsius of temperature change is required for the measurements to stabilize at each desired depth, before recording the three measurements.
