Calibration
This section describes the basic calibration method of each measurement parameter using
OAKTON 200 series Handheld meters and conductivity electrode.
Conductivity Calibration
Calibration is necessary for accurate electrical conductivity measurement. To perform
conductivity calibration, follow the procedure detailed below:
Prerequisites
Clean the conductivity electrode with DI (deionized) water and wipe it with tissue paper.
Switch on the EC meter and plug in the conductivity electrode.
Prepare standard solution required for calibration.
Press the
key to keep the EC meter in
COND
mode.
Dip the conductivity electrode in the standard solution till the hole at the upper part of the
electrode is immersed.
Salinity, TDS, and resistivity of a sample solution are calculated from the measured value
of conductivity.
In conductivity calibration mode, the default calibration method is Auto calibration. If you
like to change it to manual calibration method, refer P1.3 calibration mode setup on
page 24.
For second or multiple point calibration, clean the conductivity electrode with DI water and
follow the same procedure.
If you are performing multiple point calibration, calibrate to the lowest conductivity first and
then move to increasing conductivity values. This minimizes cross contamination.
To abort an ongoing calibration process at any point of time, press the
key.
