Conductivity measurement

21

■

Conductivity measurement

The conductivity cell can be used to measure the conductivity, salinity, TDS, and
resistivity of a sample. Salinity, TDS, and resistivity are calculated from the measured
value of conductivity.

Press the 

 key to select the measurement parameter (refer to "Changing the

measurement parameter" (page 11)).

The basic steps are the same for all measurement parameters, however, some settings
and operations are only valid for specific measurement parameters. Select the settings
and perform the steps that show the mark of the parameter you want to measure.

< Examples >

: Conductivity measurement

: Salinity measurement

: Total dissolved solids measurement

: Resistivity measurement

: All measurement parameters
