User Guide
Incorporating a flat sensor, the Elcometer 138 Bresle Salt Meter measures the conductivity of a solution
from a single drop of the sample, then automatically converts this to show the density of salts.
The Elcometer 138 Bresle Salt Meter can be used in accordance with the following two test methods:
Ÿ ISO 8502-6 / ISO8502-9
Ÿ US NAVY PPI 63101-000 (Rev 27)
It can also be used in accordance with ISO 8502-11; AS 3894.6-A and SSPC Guide 15.
R
For IMO PSPC , the surface salts should be measured and recorded. The Elcometer 138 Bresle Salt
a
Meter can be used for this.
2 BOX CONTENTS
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.

The Elcometer 138 Bresle Salt Meter 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.
