NEWPORT's SM-10 Digital Salt Analyzer provides a rapid, economical
method for testing sodium chloride in food products. Developed
expressly for food industry, the SM-10 eliminates the
need for costly, time consuming titrations by using a dip style
electrode for analysis. Factory calibrated for % NaCl in water,
a front panel mounted adjustment knob permits recalibration
for the specific product being tested. Two switch selectable
ranges 0-2% and 0-20% provide high resolution digital reading
of tested salt values.
SM-10's describe the non-linear relationship between
conductivity and percent salt adjusted for temperature. The
specific factory calibration is for NaCl in water.
Soak samples of dry or surface salted foods in distilled water
to produce a sample fluid or use packing fluid from wet packed
products for analysis. When the electrode is dipped in the sample,
the percent of salt concentration is displayed digitally. Display
will read "1" if the concentration is over scale.
Recalibration for salts (other than NaCl in H20)
with similar Conductivity vs % Salt Concentration characteristics
is possible using the calibration adjustment on the front panel.
Adjust the digital value to match the titration results. This
provides a single point recalibration.
at differing rates in different solvents. Each has a unique Conductivity
vs % Salt graph. While similar, these are not precise duplicates.
The SM-10 can be calibrated to match a single one titration
point. A chart is needed if full range values are required.
