Solinst

107 TLC Meter

Temperature, level and conductivity meter for profiling wells and open water, with readings shown on an LCD on the reel.

Conductivity from 0 to 80,000 µS/cm, displayed as specific conductance standardized to 25 °C
Temperature accuracy of ±0.2 °C, with readings in °C or °F
Water level and probe depth read from laser-marked PVDF flat tape, in lengths up to 300 m (1000 ft)

Quantity

Overview

The Solinst Model 107 TLC Meter is ideal for profiling conductivity and temperature in wells and open water, for salt-water intrusion studies, and as a general indication of contamination levels. A 19 mm (3/4") diameter probe is attached to Solinst PVDF flat tape, laser marked every 1/100 ft or each millimetre, on a sturdy stand-alone reel. Conductivity and temperature are displayed on an LCD screen on the face of the reel, while a light and buzzer activate briefly when the probe enters water, so water level and probe depth can be read directly from the tape.

Typical applications

Profiling conductivity and temperature in wells and open water
Salinity studies and saltwater intrusion investigations
Testing for water quality impairments from road salt
Tracer tests
General indication of chemical contamination level
Early warning of changes in water quality at landfills and industrial sites

Key Features

Measures temperature, water level and conductivity with one probe
Conductivity range 0 to 80,000 µS/cm, calibrated range 500 to 80,000 µS/cm
Smart probe displays specific conductance standardized to 25 °C (EC), with a temperature coefficient of 2.0% per °C
Temperature accuracy ±0.2 °C (±0.4 °F); readings shown in °C or °F
Light and buzzer briefly activate when the probe enters water; a short buzz warns when it leaves the water
Simple 1, 2, 3 or 4 point user calibration with 1413, 5000, 12,880 and 80,000 µS/cm solutions
19 mm (3/4") probe, submersible the full length of the tape, with a tape seal plug for quick replacement
Laser-marked PVDF flat tape with a dog-bone design that reduces adherence to wet surfaces; easy to repair and splice
Stand-alone reel with carrying handle, probe holder, brake, battery drawer and tape guide stored on the frame

Benefits
