INTRODUCTION
This Sper Scientic Test Tube pH Pen
(Model 850062/ 850063) is designed for easy
calibration and simple, accurate measurement.
The 12 cm long probe is capable of testing
samples even in narrow-mouthed containers.
The waterproof meter provides one-button,
three-point calibration with customizable
calibration values. Other features include
a data-hold function, automatic shuto󰀨 and
low-battery indicator. Model 850063 also
measures temperature and provides automatic
temperature compensation.

CALIBRATION
The meter should be calibrated regularly with
standard USA, NIST or DIN bu󰀨ers to ensure
accuracy. If the meter is used frequently, daily
calibration is recommended.
Voltage Range for Each Calibration Point
pH 4.00 97 mV ~ 250 mV
pH 7.00 -60 mV ~ 60 mV
pH 10.00 -250 mV ~ -97 mV
Calibration Procedure
1. Press POWER button to turn the meter on.
2. Pour the pH bu󰀨er into a clean container
and place the electrode into the bu󰀨er. We
recommend starting with a middle range
bu󰀨er such as pH 7. Make sure the electrode
is completely immersed in the bu󰀨er.
3. Press CAL to enter Calibration Mode.
“CAL” displays for one second, followed by
the pH value. Model 850063 also displays
the temperature.
Calibration is necessary and should be
done regularly, recommended everyday
if the meter is used often. The unique
calibration design of the meter features
automatic buffer recognition to avoid errors.
CALIBRATION MODE (CAL)

1. Power on the meter.
2. Place the electrode into a buffer solution
(4,7or10), pH7 should be calibrated first
and then 4 or 10 pH for better accuracy
3. Press " " to enter pH calibration
mode. The icon "CAL” will appear on the
LCD for one second and then pH value
(4,7 or 10) will be displayed on the LCD.
8691/8692 Calibration
4. If probe or buffer is in error:
If the buffer is incorrectly inserted or
the probe is damaged or the probe
can not detect buffer in below voltage
range, the meter will escape calibration
mode automatically after 10 seconds.
Text "End" will appear on
the LCD in one second
and then will go back to
normal status.

4. If the displayed value is di󰀨erent from the
standard bu󰀨er that you are using, press
and hold down HOLD to change the value.
Each bu󰀨er value may be adjusted within a
specied range:
a. 4.00 pH may be adjusted from
3.50 to 4.50
b. 7.00 pH may be adjusted from
6.50 to 7.50.
c. 10.00 pH may be adjusted from
9.50 to 10.50.
5. When the value stabilizes, the meter will
save the value. “SA” displays.
6. “End” displays and the meter returns to
Normal Mode.
7. Rinse the probe with deionized water,
a rinse solution, or tap water.
8. Repeat steps 2-7 to calibrate the meter with
the remaining two bu󰀨er solutions.

PH 4.00 : 97mV..... 250mV
PH 7.00 : - 60mV..... 60mV
PH10.00 : - 250mV..... -97mV

5. If the probe recognizes the buffer:
If the probe successfully recognizes the
buffer, the buffer pH value (4 or 7 or 10)
will appear on the display in 2 seconds.
If the calibration buffer is not 4,7,10 but
another value, such as 7.01, just
press " " to change the value.
7. To save the calibration value:
When the electrode reads a stable value
and user stops pressing any keys, the
meter will automatically save the value
and then escape the calibration mode.
6. The adjustable cal. point range for 4.0
pH is from 3.50 to 4.50. For 7.0 pH is
from 6.50 to 7.50. For 10.0 pH is from
9.50 to 10.50

Note…
If there is an error due to a damaged
or incorrectly inserted probe, or if the
bu󰀨er voltage out of range, the meter will
automatically exit calibration mode in 10
seconds. “End” displays for one second and
the meter returns to Normal Mode.
MEASUREMENT PROCEDURES
Note…
The electrode should be soaked for at least
10 - 30 minutes in KCL solution before rst
use, or any time it has dried out. It is normal
for white crystals to be present on the cap or
electrode assembly.

CARE AND MAINTENANCE
The electrode should be soaked for at least
30 minutes before rst use, or any time it has
dried out. It is normal for white crystals to be
present on the cap or electrode assembly.
Always handle and store the electrode
with care.
• Do NOT touch, wipe or rub the glass bulb.
• The pH glass bulb must always be kept
moist. Place it in the protective storage bottle
whenever it is not in use.
• Rinse the electrode in deionized water, a
rinse solution, or tap water before each use.
• Rinse the electrode in deionized water
between measurements.

15
If the electrode has been exposed to a solvent
immiscible with water:
• Clean it with a solvent miscible with water,
such as ethanol or acetone.
• Rinse the electrode carefully with water.
