SALINTEST
HI98203
Salinity Concentration
Pocket-sized Meter
GENERAL INFORMATION
The SALINTEST utilizes a sodium ion-selective
glass electrode to determine the activity of sodium
ions in solution.
When dissolved, NaCl ionizes to form Na+ and
Cl- ions. Measurement of Na+ ion concentration is
an indicator of the concentration of NaCl.
The relationship between the SALINTEST reading
and the g/L NaCl scale is shown in the logaritmic
chart below.
A double junction reference is used to ensure a
highly stable reading.
If you suspect that the calibration has drifted, you
can recalibrate the meter by using HI7081 or a
solution of known concentration (adjust the reading
with the calibration trimmer).
HOW TO USE THE CHART
• Locate the pNa reading on the horizontal axis
of the chart.
• Move vertically upwards to intersect with the
45º line.
• Move horizontally and read the “g/L of NaCl”
value.
E.g.
Display = .42
g/L NaCl = 22
OPERATION
• Remove the protective cap and
turn SALINTEST on by sliding
the ON/OFF switch located on
the top of the meter.
• Immerse it into the solution to
be tested without exceeding the
maximum immersion level.
• Stir gently and wait for the reading to stabilize.
• Read the value on display and use the chart to
convert the reading to g/L NaCl.
• After use, switch the meter off, rinse the electrode with water and replace the protective cap.
• Large differences in pNa readings (±0.1) could
be due to a dry electrode or lack in calibration.
• To improve performance, immerse the meter
in HI7081 solution for a few minutes, at least
once a week.
CALIBRATION
• Immerse the tester in the HI7081 (30 g/L
NaCl) calibration solution, without exceeding
the maximum immersion level.
• Allow the reading to stabilize and with the supplied
screwdriver adjust the
calibration trimmer on the
meter side to read “ .30”.
Calibration is now complete.
MAINTENANCE
In case of erroneous reading even after an
accurate calibration, the reference junction can be
contaminated or clogged.
Pull out 2 mm (1/8’’) of
the cloth junction to renew
the electrode reference (it
is recommended to cut
the cloth leaving always
at least 2 mm -1/8’’ over
the reference compartment)
and re-calibrate the meter.
The cloth junction can be pulled out approximately
20 times. After that, the electrode should be
replaced.
ELECTRODE REPLACEMENT
For replacing the electrode, contact your local
Hanna Instruments Office.
BATTERY REPLACEMENT
If display fades or the SALINTEST switches off,
the batteries must be replaced.
Slide off the battery compartment cover and replace
all four 1.5V alkaline batteries while paying
attention to the correct polarity.
Batteries should only be replaced in a non-hazardous area and using the battery type specified
in this instruction manual.
