Salt Content of Water Sources
Quantity values for the contents present in the water are given in dif-
ferent units; therefore, conversion to the measuring units of the sys-
tem is necessary.
In the case of the WTC 1600 the presence of salt ions is deduced from
the continual measurement of the conductivity.
The conductivity values provide information on the salts dissolved in
the water; thereby quantitative information is given on the material
contents.
The conductivity value of 2 000 µS/cm (limit value of the WHO) is re-
garded as the limit for a certain water being defined as drinkable, i.e.
using this definition, water with a higher conductivity value is consid-
ered unfit for drinking.
NOTE The conductivity limits are country-specific and
can differ from the above mentioned value.
The following table enables making an approximate assessment for
converting ppm to µS/cm.
