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 0-80,000 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 Edge. (See Model 3001 LTC Levelogger Edge Data Sheet).

 

Conductivity Made Easy

 

Rugged PVDF Flat Tape

The high quality PVDF flat tape reels smoothly, remains flexible and hangs straight in the well, irrespective of temperature. The flat tape is mounted on a sturdy, well-balanced Solinst reel, with a convenient battery drawer for the 9 Volt alkaline battery. Permanent laser markings each 1/100 ft or millimeter allow accurate readings.

Standard stainless steel conductors and copper coated stainless 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.

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.

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.
