Conductivity Measurements
The TLC Meter uses a 'smart' conductivity sensor with platinum electrodes to read conductivity. The conductivity is displayed on the rotating screen along with the associated temperature measurement. The 'smart' conductivity probe displays conductivity automatically standardized to 25°C, i.e. specific conductance. The conductance temperature coefficient is 2.0% per °C.
Calibration is simple, using 1413 µS and 12,880 µS solutions for single or two point conductivity calibration.
Temperature Measurements
The TLC Meter operates in a range from -15°C to +50°C (23°F to 122°F). You may choose to have the readings displayed on the LCD screen in °C or °F. The 'smart' TLC probe automatically adjusts the measured conductivity values to display as specific conductance. This provides standardized repeatably comparable measurements.
When the probe is turned on, the LCD screen displays both conductivity and temperature.
Level and 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 When the TLC Meter is withdrawn from the water, a short buzz gives a warning that the probe is now out of water.
A Tape Guide/Datum allows the depth measurement to be read at the marked position on the Tape Guide, to give reliable, repeatable, accurate depth measurements when profiling a well. The Tape Guide protects the tape from damage on rough edges of well casing.
High Quality Tape
The high quality PVDF tape reels smoothly, remains flexible and hangs straight in the well, irrespective of temperature. The 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.
Stranded 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.
