Product information

The Salinity Meter is used to check the IMO D1 standard is for ballast water exchange. The D1 standard specifies the volume of water to be exchanged and the target salinity of the ballast water, typically >30ppt.


If the sample shows results >20.0ppt. Dilute the sample 50:50 with distilled water and multiply the result by 2.

For calibration purposes, 12.88mS is equivalent to 7.4 to 7.4 ppt Salinity.
