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 that rotates for ease of
reading.
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
Conductivity Made Easy
• Tape lengths to 1000 ft (300 m)
• Rugged Solinst reel and accurate PVDF laser marked tape
• Probe diameter 3/4" (19 mm)
• Display that rotates for easy reading
• Standard 9V alkaline battery gives 90 hrs. of use
• Auto-Off after 8 minutes
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.
Stranded stainless steel conductors and copper coated steel conductors resist corrosion, provide strength and are nonstretch.
They make the tape easy to repair and splice. The dogbone 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 rotating 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.
Applications
• Profiling conductivity and temperature in wells and open water
• Salinity studies
• 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
- Industrial sites
Water Level & Depth Measurements
When the zero point of the probe enters water, an electric circuit is completed, briefly activating a buzzer and blanking out the screen for about 1 second. The depth to water is then read off the tape. When the TLC Meter is withdrawn from the water, a short buzz gives a warning that the probe is now out of water.
Water Temperature Measurements
The TLC Meter operates in a range from -15ºC to +50ºC (23ºF to 122ºF). You may choose to have the readings displayed
on the LCD screen in ºC or ºF. Accuracy is +/- 0.2°C in Celsius, or +/- 0.4°F in Fahrenheit. The ‘smart’ TLC probe automatically adjusts the measured conductivity values to display as specific conductance standardized to 25ºC.
