Salinity Calibration
15
● Salinity Calibration
Calibration is necessary for accurate salinity measurement. To perform salinity 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 meter in SAL mode.
• Dip the conductivity electrode in the standard solution till the hole at the upper part of the
electrode is immersed.
• Before salinity calibration, set the required salinity method. In LAQUA-EC1500 benchtop
meter, available salinity methods are;
-NACL
-SEA.W (Sea water)
• To set a desired salinity method, refer “P3.2 Salinity Type Setup” on page 35.
• User can adjust the salinity value by calibration.
To abort an ongoing calibration process at any point of time, press the key.
