1 OVERVIEW
Incorporating a flat sensor, the Elcometer 138 Bresle Salt Meter has been designed primarily for use in
accordance with ISO 8502-6 / ISO8502-9. It measures the conductivity of the sample but displays the
surface density of salts. The measured conductivity is converted to surface density of salts using the
ISO Salt Mix or IMO PSPC equivalent NaCI conversion factors below, dependent on the measurement
mode selected, based on an area of 12.5cm and a sample volume of 3ml.
For detailed information on taking measurements in accordance with ISO 8502-6 /ISO8502-9, please
refer to the user guides for the Elcometer 138 Bresle Salt Kits.

Note: The Elcometer 138 Bresle Salt Meter measures aqueous solutions. The meter is NOT designed to measure solids, organic
solvents, surfactant, oil, adhesive, alcohol, strong acids (pH: 0 to 2) or strong alkalis (pH: 12 to 14). The life of the sensor
will be extremely short if these substances are measured.
