Parameters that can be measured in salt water with the help of a PoolWaterLAB

The following parameters can be tested in salty water

 

Parameter	Fresh water	Saltwater	Seawater
Active oxygen	✔	✔
Alkalinity	✔	✔	✔
Bromine	✔	✔
Chlorine	✔	✔
Chlorine dioxide	✔	✔
Cyanuric acid	✔	✔
Total hardness	✔

* Special case pH measurement

Depending on the salt content of your sample, the measurement result must be corrected according to the following scheme:

1 molar = -0,21 pH
2 molar = -0,26 pH
3 molar = -0,29 pH
where: 1 mol salt (NaCl) = 5.8 % = 58.4 g/l

Pools with salt electrolysis are not affected.
In salt electrolysis, a maximum of 7 g/l salt is used, far less than 1 mol (58.4 g).
