Storage cap
The probe must not be allowed to
dry out. Always place storage cap
back onto probe tip after each use
and ensure it contains either water
or pH 4.0 solution.

Turn pen on
Press power button. The last measurement is
recalled for 3 seconds.
To turn pen off
Press and hold the power button until OFF is
displayed.
NOTE: The pen will automatically turn off after
4 minutes to conserve battery power.
Measure pH
Remove storage cap, place probe in solution and
wait for reading to stabilize.

3.0 IMPORTANT - pen probe care
pH probes do not last forever. They age through normal use and will eventually
fail. The lifetime of a probe depends on the environment it is used in and the way
it is treated. To ensure you receive a long life from your pen, please ensure you
follow the guide below.
Storing the pen
When storing the pen the probe tip must be kept moist.
To prepare the probe for storage, place a small amount of clean water (never
distilled or deionised water) or pH 4.0 solution into the wetting seal inside the
storage cap. Then place the seal and cap over the probe tip.
Long term storage
For long term storage, place the pen upright in a glass of tap water with the
storage cap off to ensure constant hydration.
If the probe has been accidentally allowed to dry out:
The probe must be ‘hydrated’ for 24 hours in fresh clean water (never distilled
or deionised water). Following this; carry out a calibration to check if the probe
has already suffered permanent damage.
4.0 Cleaning
To ensure accurate readings the probe needs to be rinsed in water before
replacing the storage cap and cleaned regularly using the following instructions.
Rinse probe tip under fresh water.
Fill small container with clean water.
Add a small amount of Bluelab pH Probe Cleaner
or mild detergent (dish washing liquid).
Gently stir the probe tip in the mixture.
Ensure that you do not ‘knock’ the pen on the side
of the container as this may cause damage to the
glass probe. Rinse well under fresh running water
to remove all traces of the detergent mixture.
If the probe requires removal of heavy
contamination:
Gently brush around the glassware with a few
drops of Bluelab pH Probe Cleaner or mild
detergent (dishwashing liquid) and a soft
toothbrush.
Rinse well under fresh running water to
remove all traces of the detergent mixture.
Calibration of the probe is required after every
clean.
See the pH calibration in section 6.0. Place
storage cap back onto the probe.

DO NOT let the probe tip dry. IF IT DRIES IT DIES!
DO NOT knock the pen; this will break its external glass bulb or
internal glass tube.
DO NOT touch the glass bulb with your ngers as this will
contaminate the glass.
DO NOT plunge a cold probe into a hot liquid (or visa versa) -
sudden temperature changes can crack the glass and permanently
damage the pen.
DO NOT immerse in oils, proteins or suspended solids that will leave
a coating on the glass bulb.

5.0 Battery replacement
The pH pen is powered with 1 x AAA alkaline battery. Do not use rechargeable
batteries. A low battery warning is indicated by a battery symbol appearing on the
screen. Only remove the battery cap when the batteries require changing. Battery
life is expected to be 350 hours.
To remove old battery
Undo battery cap fasteners. Remove battery cap and tip out
the old battery.
Check for corrosion
Flat batteries may leak and cause corrosion. Check battery
contacts and the battery for any sign of corrosion. Battery
contacts should be cleaned first if corrosion is found before
proceeding to step 3.
Fit new battery
Insert the new batteries positive (+) end down into the body.
Ensure waterproof battery cap seal is clean
Seal will fail if any dirt is present.
Replace battery cap
Tighten fasteners on battery cap until there is no space left
between the cap and body. This ensures the unit remains
100% waterproof.

7.0 Error messages
The following error messages appear for the following reasons.
6.0 Calibration
pH calibration is required before first use to ensure that the first reading is accurate.
Calibration is also required when:
•Thecheckmark/tickhasdisappearedfromtheLCDscreen(30daysafterlastcalibration)
•Thereadingisdifferentfromwhatyouexpected
•Aftercleaning
•Afterchangingthebatteries
pH 7.0 and pH 4.0 solutions are required for calibration. You may also calibrate using
pH 7.0 and pH 10.0 solutions if your readings will normally be higher than 7.0 pH.
Excluding first use, YOU MUST CLEAN the probe
before calibrating.
See section 4.0.
Rinse probe in fresh water and place in pH 7.0
solution.
Wait for reading to stabilize.
Press the cal button until CAL is displayed.
Release button. When CAL 7 is displayed, 1 point
calibration is complete.
Rinse probe in fresh water and place it in either pH
4.0 or pH 10.0 solution (use pH 10.0 solution if you
expect to measure above 7.0 pH).
Wait for reading to stabilize.
Press the cal button until CAL 4 or CAL 10 is
displayed.
CAL 4 or CAL 10 should be displayed (depending on what
solution you are calibrating in). The check mark/tick is
displayed when a 2 point (or 3) calibration is completed.
NOTE: For a three point calibration repeat the steps using
4, 7 then 10 solution.

The instrument is only as accurate as the probe is clean!
Bluelab cleaning kits
Probe cleaning is one of the most important parts of owning and operating any Bluelab
meter, monitor or controller. If the probe is contaminated (dirty) it affects the accuracy of
the reading displayed.
The probe surface is where the instrument takes the reading of the solution. The information is sent back
from the probe to the electronic brain of the instrument.
A calculation is then done in the instrument’s brain or micro computer and a reading is displayed. If the
information sent back from the probe is inaccurate due to probe surface contamination then the reading will
be inaccurate. Cleaning the probes is a very easy task and will prolong the life of the probes.
