INSTRUCTION MANUAL
Care & Maintenance
• To improve accuracy, immerse the meter in HI7081
solution for a few minutes at least once a week.
• Erroneous readings after accurate calibrations may
indicate a contaminated or clogged junction. Pull
out 2 mm (1/8”) of the cloth junction to renew the
electrode reference. Cut the cloth leaving at least
2 mm (1/8”) over the reference compartment and
recalibrate the meter.
The cloth junction can be pulled out approximately
12 times.
PULL OUT
Battery Replacement
When the display fades or the meter switches off, the
batteries need replacing.
To replace the batteries:
1. With the meter off, slide off the battery compartment
cover.
2. Remove the old batteries.
3. Insert 4 new 1.5V Alkaline batteries in the battery
compartment while paying attention to the correct
polarity.
4. Replace the battery compartment cover.

General Description & Intended Use
HI98203 is designed to help users monitor the
concentration of sodium chloride in aquaculture
applications and salt concentration in marine fish tanks
and aquariums.
The meter has a one-point calibration through a
trimmer on the side and is equipped with a sodium
ion-selective glass electrode that determines 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 double junction reference ensures highly-stable
readings.

Calibration
1. Remove the protective cap and slide the ON/OFF
switch to turn the meter on.
2. Immerse the meter in HI7081 30 g/L NaCl calibration
solution, paying attention not to exceed maximum
immersion level. Allow the reading to stabilize.
3. When the reading is stable,
use the supplied screwdriver
to adjust the calibration
trimmer on the side until the
display shows “.30”.
Calibration is complete.
To avoid calibration drift,
refer to Care & Maintenance
section. A solution of
known concentration can
also be used to recalibrate
the meter.

Measurement
1. Remove the protective cap.
2. Slide the ON/OFF switch to turn the meter on.
3. Immerse the meter into the solution to be tested, paying
attention not to exceed maximum immersion level.
4. Stir gently and wait for the reading to stabilize.
5. Use the chart to convert read value to g/L of NaCl.
6. After use, switch the meter off, rinse the electrode
with water, and replace the protective cap.
Note: For accurate readings keep the electrode
hydrated and calibrate frequently.
How to Use the Chart
The logarithmic chart below converts readings into g/L
of sodium chloride.
1. Locate the reading on the horizontal axis.
2. Move vertically upwards to intersect with the 45° line.
3. Move horizontally and read the g/L of NaCl value.
E.g. Read value = .42
converted g/L NaCl value = 22
1 Division = 0.02
