Conductivity, Temperature, Level and Depth Measurements


Water Level & Depth Measurements

When the zero point of the probe enters water, an electric circuit is completed, briefly activating a buzzer and light 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 When the TLC Meter is withdrawn from the water, a short buzz gives a warning that the probe is now out of water.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.


Water Temperature Measurements

The TLC Meter operates in a range from -15ºC to +50ºC (5ºF 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. This provides standardized, repeatably comparable measurements.

The full temperature range of the TLC Meter is -20ºC to 60ºC. The minimum temperature display is -20ºC; a temperature below -20ºC will display ^^^^^^. The maximum temperature display is 60ºC; a temperature above 60ºC will display ^^^^^^.

When the probe is turned on, the LCD screen displays both conductivity and temperature.
