English

1.0 Before use begins

Hydrate in water for 24 hours before you start using the pen.

Calibrate the pen before you start using the pen.

See section 6.0

2.0 To operate

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.

To hold reading

If you want to “hold” the reading on the screen, short

press the power button. To exit the hold function

press the power button again.

To change temperature units

Hold down the units button for 3 seconds until the

temperature units start ﬂashing. Short press the units

button again to cycle between °F and °C. To exit this

mode don’t press anything for 3 seconds.

NOTE: You can change units while in hold mode by

holding down the units button.

Rinse and replace storage cap

To ensure accurate pH readings always rinse the

probe in clean fresh water before replacing the cap.

The cap is tight to ensure a good seal and should click

when on correctly.

3.0 IMPORTANT - pH 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 pH pen

When storing the pH 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.

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 ﬁngers 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.

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.

Detergent

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:

•The check mark/tick has disappeared from the LCD screen (30 days after last calibration)

•The reading is different from what you expected

•After cleaning

•After changing the batteries

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.

Bluelab pH Probe Calibration

and Cleaning Kit contents:

Bluelab cleaning kits

The instrument is only as accurate as the probe is clean!

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 aects 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.
