Preliminary Examination
Remove the meter and accessories from the packing material and examine it carefully. If you require any further information, please contact Hanna Instruments technical support team at tech@hannainst.com. Each HI98203 is supplied with:
- Protective cap
- Calibration screwdriver
- 1.5V Alkaline battery (4 pcs.)
- Quality certificate and Instruction manual
Note : Save all packing material until you are sure that the meter works correctly. Any damaged or defective item must be returned in its original packing material with the supplied accessories.
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.
Specifications
- Range 0.00 to 1.00 pNaCl (58.4 to 5.84 g/L NaCl)
- Resolution 0.01 pNaCl
- Accuracy ±0.02 pNaCl (@ 20 °C / 68 °F)
- Calibration Manual , one point
- Environment 0 to 50 °C (32 to 122 °F) RH max. 95%
- Battery type 1.5V Alkaline
- Battery life Approximately 500 hours of continuous use
- Dimensions 175 x 41 x 23 mm (6.9 x 1.6 x 0.9”)
- Weight 95 g (3.4 oz.)
Calibration
- Remove the protective cap and slide the ON/OFF switch to turn the meter on.
- Immerse the meter in HI7081 30 g/L NaCl calibration solution, paying attention not to exceed maximum immersion level. Allow the reading to stabilize.
- 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
- Remove the protective cap.
- Slide the ON/OFF switch to turn the meter on.
- Immerse the meter into the solution to be tested, paying attention not to exceed maximum immersion level.
- Stir gently and wait for the reading to stabilize.
- Use the chart to convert read value to g/L of NaCl.
- 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.
- Locate the reading on the horizontal axis.
- Move vertically upwards to intersect with the 45° line.
- Move horizontally and read the g/L of NaCl value.
E. g. Read value = .42
converted g/L NaCl value = 22
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.
Battery Replacement
When the display fades or the meter switches off, the batteries need replacing.
To replace the batteries:
- With the meter off, slide off the battery compartment cover.
- Remove the old batteries.
- Insert 4 new 1.5V Alkaline batteries in the battery compartment while paying attention to the correct polarity.
- Replace the battery compartment cover.
Note: Do not mix old and new Alkaline batteries. Only use specified battery type. Dispose of old batteries in accordance with local regulations.
