Why measure Calcium value?
Calcium is necessary for plants and animal nutrition, as it is an essential constituent of bones, shells, and plant structures.
In seawater, invertebrates (corals, shellfish, etc.) and calcareous algae need a sufficient calcium content to ensure optimal growth.
The natural calcium content in seawater is 400-420 mg/L.

The HI 758 mini-photometer is specially designed for measuring calcium in seawater.
Its wide range allows measurements between 200 and 600 mg/L.
