Model 107 TLC Meter

The Model 107 TLC Meter enables accurate profiling of water temperature and conductivity in aquifers, and open water bodies.

Using platinum electrodes, the 19 mm (3/4″) diameter TLC Probe measures conductivity readings from 0 – 80,000 µS/cm. The readings are shown as electrical conductivity standardized to 25ºC (Specific Conductance). Accuracy is 5% or 100 µS, whichever is greater.

Conductivity and associated temperature readings, from -15ºC to +50ºC (23ºF to 122ºF), are taken from the LCD display on the reel.

Profiling depths are read from the Solinst laser-marked flat tape, up to 300 m (1000 ft). The tape is accurately laser marked each millimeter or every 1/100 ft., and is certified traceable to national standards.

A standard 9V alkaline battery gives up to 90 hours of on-time and the electronics have an auto-off after 8 minutes of inactivity. Calibration is simple, with a single, or up to 4-point calibration option.

Salinity issues are prevalent worldwide, including saltwater intrusion due to over-pumping of wells and road salt contamination of municipal drinking water wells. The TLC meter is ideal to use in monitoring these situations, or for providing a general indication of water quality in any application.
