The Model 107 TLC Meter provides accurate, stable temperature and conductivity measurements, displayed on a convenient LCD display for easy reading. Static water level and depth of readings are read off Solinst flat tape, which is precisely laser-marked every mm or 1/100 ft. Tape lengths are available up to 300 m (1000 ft). The TLC Meter is excellent for saltwater intrusion monitoring, road salt studies, and for a general indication of contamination levels.
