Section 4: Using Win-Situ
Check the Conductivity Calibration
The conductivity sensor in the Aqua TROLL has been calibrated
during manufacturing to produce a linear response across
the operating range.
We recommend you check the specific conductivity
reading in the solution shipped with your instrument. If
the device is reading accurately, there is no need to field-
calibrate the instrument unless SOPs require it.
To perform a field calibration you will need:
4
The In-Situ Cal Cup, or other suitable container that
allows for complete immersion of the conductivity
sensor, including the temperature “button,” which
can be seen on one side of the probe. The Cal Cup is
recommended for the first calibration.
4
The calibration standard solution
supplied, or other solution of known
specific conductivity in the range 100 to
60,000 µS/cm.
The complete calibration procedure takes
only a few minutes and may be done in a
field or office/lab setting with a software connection in Win-Situ
5 or Win-Situ Mobile Software. A detailed description of the
conductivity calibration procedure, including:
• Preparation of the Aqua TROLL
• Software input
• Calculated output
• Hints for successful calibration
is in Section 5 of this manual.
For best results we
recommend you
read and follow
the conductivity calibration
procedure in Section 5 of this
Operator’s Manual.
