2.4.2 Salinity
Salinity is a measure of the total amount of salt dissolved in a body of water. It can be automatically
calculated from the conductivity and temperature detected by the multi-parameter analyzer. The algorithm
is based on the standard method for water and seawater detection (1989), and its unit output is ppt.
Salinity can be used for real-time compensation of dissolved oxygen.

2.4.3 Total dissolved solids
The total dissolved solids are also called the total amount of dissolved solids, which means the amount of
