Operation Manual
Marine Salt Testa
Digital meter for the measurement of
salinity, specific gravity and temperature

1. PRECAUTION
The Marine Salt testa is for the sole purpose of measuring the
Temperature, Salinity and Specific Gravity of natural seawater and /
or synthetic seawater. This meter has been factory calibrated and
performance tested to ensure accurate readings.
Please read the entire operation manual before using this Marine
Salt testa. Failure to read this manual prior usage may result in
equipment damage and will void the warranty.
1.1 Notes on safety
Please keep this product away from children. Ingestion of small
parts may lead to choking and serious injury. If the sensor
protection cap or battery is ingest; please consult a physician
immediately.
Be careful not to scratch the surface of the platinum-plated
sensors.
Do not use chemicals such as acetone or benzene for cleaning as
it may cause deterioration of the plastic housing.
Never attempt to disassemble or modify this product, this will void
warranty.
1.2 Notes during measurement
Always rinse the Probe Sensor before and after each test.
Make sure sensor do not contact any of the walls of the
aquarium or sump while in measurement mode. Keep sensors
at least 1cm away from all sides and bottom of the measuring
container.
1.3 Notes on storage
Avoid keeping Marine Salt testa
in high humidity environments,
direct exposure to sunlight, high temperatures, dust and
moisture to prevent damage.
Please keep sensor cap in-
place to protect the sensors when not
in use.
Always remove the batteries if tester is not use over a long
period of more than one month.

2. Product Diagram and Functions
2.1 Buttons Definition:
The ON-OFF button is use to turn the power on and off. Once
turned on, Temperature measurement is display in the LCD
Display window.
The MODE button is to select display of temperature, Salinity
or Specific Gravity measurement. Press the button once will
switch it to Salinity measurement (ppt), pressing again will
switch to Specific Gravity measurement and a third time back
to Temperature measurement in a cyclical mode. This button
is also use to change the display units of temperature (°
°°
°C/°
°°
°F,
see section 6)
The HOLD button is use to “hold” the measurement value
during a test. Pressing it again will resume continuous
measurement. This button is also use for performing
Calibration in Salinity mode. (See section 5)

4. Measurement of Salinity, Temperature and Specific
Gravity
4.1 Principle of salinity measurement
The salinity measurement principle of this product is base on the
electric conductivity measurement method. Salt exists as sodium ion
and chloride ion within aqueous solution. As the quantity of sodium ion
and chloride ion increases, the solution conductivity also increases
proportionately to the increased salt concentration. Using this principle,
salinity is determined by calculating the conductivity of a given sample.
4.2 Testing Temperature, Salinity and Specific Gravity
1. Press ON/OFF button once to switch on, temperature reading will
appear on the display.
2. Dip the PROBE SENSOR into the liquid and shake vigorously to
remove bubbles on probe.
*Note: Presence of bubbles will affect reading accuracy
3. Wait for the temperature reading untill it stops changing and for a
stablized temperature to establish. Now you can press the MODE
button to switch to Salinity measurement.
4. Wait 10 seconds and confirm the Salinity (ppt) measurement.
5. Press MODE button to display Specific Gravity measurement.
Wait 10 seconds for the Specific Gravity before reading results.
6. Press the HOLD/CAL button at anytime to “Hold” or “Freeze” the
displayed reading. Press it again to “Release” for another test.
7. After each test, rinse the sensors with distilled water between each
test and wipe it dry with a clean cloth or tissue paper.
8. After a series of tests, clean the PROBE SENSOR in mild detergent
then rinse with water throughtly. Wipe the PROBE SENSOR dry
before storing away.
9. Press the ON/OFF button to switch off. The battery saving function
will automatically shut off the meter if no activity for about 1 minute.

5. Calibration
1. Perform calibration regularly or before a series of tests.
2. Use only 30ppt standard solution for this procedure.
3. Make calibration only in liquid of between 15 to 30°C
4. Switch on unit and press MODE button once to switch to salinity
mode (ppt).
5. Dip the sensor into 30ppt solution centrally; making sure the sensor
does not contact the bottom or sides of the bottle.
6. While the sensor is in the solution, press and hold-down
HOLD(CAL) button for about 15 seconds or until it display shows
C A L flashing.
7. In a while, display will show 30ppt and return to normal measuring
mode.
8. Calibration is completed
9. If display show 31, 32 or any other values, repeat the calibration.
Note: Never perform calibration if unit is not dip into 30ppt solution, as this
will cause inaccuracy to the unit. If reading is wrong, repeat this calibration
procedure.
6. Temperature display Selection (°C / °F)
1. Switch on the unit. Ensure display is in the temperature mode.
2. Press and hold-down MODE button until display shows °F.
3. Release the button, °F reading will be displayed everytime.
4. To switch to °C temperature display, repeat step 1 to 3.

7. Replacement of the Battery
When the sign appears on the LCD display, the batteries will need
replacement. The unit will automatically shut-off when battery life is out.
How to replace the batteries
1. Uscrew the battery cap and open it. Pull out the battery holder, Take
a note at the directions of each battery placed and remove all of
them.
2. Replace with two (2) new batteries (CR2032H or equivalent)
ensuring each battery’s polarity are placed in direction (positive ‘+’
sign face up as shown below).
3. Switch on power to confirm whether the batteries were place
correctly, replace the cover.
