INTRODUCTION
The Sper Scientic Large Display Salinity
(Model 850036) and Conductivity (Model
850037) Pens provide highly stable and
accurate readings with a large LCD that
simultaneously displays the parameter
being measured and temperature in
°C or °F. The pens are designed for simple
one-hand operation. The case is IP65
waterproof, and will oat if accidentally
dropped into the water.
Salinity is displayed not as a percentage
but as parts per thousand (ppt), which
is approximately grams of salt per liter
of solution.
Conductivity is displayed as mhos
per centimeter (M/cm) or siemens
per centimeter (S/cm). Because a mho
(or siemen) is a large unit, microsiemen
or millisiemen typically is used (µS/cm,
mS/cm).

Range 2 10.1 to 70.0 ppt

12
To manually select the measurement range:
1. Press SET to turn the pen on.
2. Press ▲ for more than 2 seconds to
select range 1. Press ▲ for more than
2 seconds to select range 2.
CALIBRATION
Selecting the Calibration
Standard Solution
For best results, select a NaCl standard
near the sample value that you are
measuring. Alternatively, use a calibration
solution value that is approximately ⅔ of
the full scale of the measurement range
that you plan to utilize.
Do NOT reuse the calibration solution.
Contaminants in the solution will a󰀨ect the
calibration and the accuracy. Use fresh
solution each time.
The previous calibration data will be
replaced after re-calibrating. However,

13
the pen will retain the calibration data
for other ranges that have not yet been
re-calibrated.
Selecting the Calibration Schedule
Calibration is necessary and should be
performed regularly. Soak the probe for 15
minutes before calibration or measurement
to minimize drift. If the pen is used in the
mid ranges, calibrate the unit monthly.
If the measurement is performed at
extreme temperatures or within the
concentration listed below, calibrate
the unit weekly.

Salinity Pen < 0.10 ppt > 5.0 ppt

14
Salinity Calibration
1. Place the probe into deionized or
distilled water for about 30 minutes to
rinse the probe.
2. Select the NaCl standard for calibration.
3. Pour 3 cm (deep) of solution into two
separate containers (A & B).
4. Press SET to turn the pen on.
5. Rinse the probe in one of the
containers. Gently stir the probe.
6. Dip the rinsed probe into the other
container. Tap the probe on the bottom
of the container to remove air bubbles.
Let the probe stabilize to the solution
temperature (allow 15 minutes).
7. Press CAL for more than 2 seconds to
begin calibration. “CAL” and the salinity
value of the solution will ash on the LCD.
8. Press ▲ or ▼ to adjust the value on the
primary display to match the value of
the standard bu󰀨er. You can adjust the
salinity reading ± 30% from the detected
value. If the detected value and the
standard value di󰀨er by more than ±
30%, clean or replace the pen.

15
9. When “CAL” stops ashing on the
LCD, press SET for less than 1 second
to conrm the value. The pen will
return to Measurement Mode for salt
measurement. To exit Calibration Mode
without saving, press SET for more than
2 seconds. This allows you to retain the
pen’s previous calibration data for the
current range as you proceed. If “CAL”
ashes on the LCD continually, check
that the calibration solution is stable and
that the input value (Step 8) is correct.
10. Repeat Steps 1-9 for other ranges
as needed.
Note…
If the standard value is over the measuring
range or 10% less, the displayed value will
be equal to the range limit or 10% of the
range limit.

16
MEASUREMENT PROCEDURES
1. Remove the probe cover from the pen.
2. Press SET to turn the pen on.
3. The pen defaults to auto-ranging mode.
The auto-ranging function determines
and selects a range that will provide the
greatest resolution and accuracy.
4. To manually select the measurement
range: Press SET to turn the pen on.
Press ▲ for more than 2 seconds to
select range 1. Press ▲ for more than
2 seconds to select range 2.
Note...
Accuracy is a percent of full-scale; use
your pen in the lowest range to achieve
the greatest accuracy. Error codes
E02/E03 will appear on the LCD if the
measured value is below or above the
limit value. Please re-select the range.

17
5. Rinse the probe tip with de-ionized or
distilled water before use to remove
any impurities adhering to the probe. If
the probe tip is dehydrated, soak it for
30 minutes to prevent contaminants
from slowing down the measurement
and accuracy.
6. Immerse the probe tip completely into
the sample. Ensure that there are no
air bubbles trapped in the probe slot.
Gently stir the probe to remove air
bubbles, ensuring that the probe tip
is submerged while stirring.
7. Stir the probe gently to create a uniform
sample. Wait about 15 minutes for the
reading to stabilize.
8. The unit of measure will ash on the
LCD to indicate that the pen is in
Measurement Mode. When the
reading is stable, the unit of measure
will stop ashing.
Hold Function
1. Press HLD to freeze the current
readings on the display. “Hold” will
appear on the LCD.

18
2. Press HLD again to release the
hold function.
Turning the Pen O󰀨
1. Press SET to turn the pen o󰀨 from
Measurement Mode.
2. To turn the pen o󰀨 from Setup Mode,
press SET for more than 2 seconds
to return to Measurement Mode, then
press SET again.
Auto Power O󰀨
1. To save battery life, the pen will
automatically turn o󰀨 after 20 minutes
of inactivity. To disable this function:
2. Press SET to turn the pen o󰀨.
3. Press SET and ▼ simultaneously until
“n” appears on the LCD. Release the
keys to return to Measurement Mode.
Auto-power-o󰀨 is now disabled.
Note…
The auto-power-o󰀨 function will be
enabled each time the pen is turned o󰀨.

ERROR CODES
Salinity
- - - The pen is in manual ranging 1 but
the salinity measurement is higher
than 10.0 ppt; Press ▲ for more
than 2 seconds to change to manual
ranging 2 or auto-ranging mode.
E03 The salt value is over the range limit
(70.0 ppt) or the pen is damaged;
Put the pen in standard bu󰀨er
solution (the bu󰀨er concentration
must be lower than the range limit).
If E03 still appears, send the pen to
Sper Scientic for repair.
E04 Error in measuring original data
(damaged temperature sensor,
temperature out of specications
or salinity error). E04 will disappear
when the original error is resolved.
