Salinity calibration
Calibration is necessary for accurate salinity measurement. To perform salinity calibration
using LAQUA 220 conductivity handheld meter, 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
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 EC220 handheld
meter, available salinity methods are;
-
NACL
-
SEA.W
(Sea water)
• To set a desired salinity method, refer “P3.2 select salinity type” on page 33.
• User can adjust the salinity value by calibration.
• For second or multiple point calibration, clean the conductivity electrode with DI water and
follow the same procedure.
• To abort an ongoing calibration process at any point of time, press the
key.
