2.0 IMPORTANT - Bluelab pH Probe care
pH probes DO NOT last forever. They age through normal use and will eventually fail. The
life time of a pH probe depends on the environment it is used in and the way that it is
treated. To receive a long life from your pH probe, ensure you follow the guide below.
pH probes contain glass and are therefore FRAGILE. With good care, they will give a long
service life.
Bluelab pH Probe
DO NOT let the pH probe tip dry.
DO NOT bend the probe; this will break its internal glass tube.
DO NOT knock the probe; this will break its internal glass tube or external glass bulb.
DO NOT plunge a cold pH probe into a hot liquid - sudden temperature changes can crack
the glass and permanently damage the probe.
DO NOT immerse in oils, proteins or suspended solids that will leave a coating on the glass
bulb.
Always remove pH probe storage cap before use
1. Grip the top of the cap and gently twist the base one rotation
clockwise to loosen slightly.
2. Next slowly slide the cap off the pH probe. DO NOT
completely remove the base of the cap from the top of the
cap.
Storing the pH probe
When storing the pH probe, the pH probe tip must be kept moist.
To prepare the pH probe for storage, add enough Bluelab pH
Probe KCl Storage Solution to the storage cap so the probe tip is
covered. Then replace the cap and store in a secure place. DO
NOT use RO (Reverse Osmosis), Distilled or De-ionized water. Pure
water changes the chemistry in the reference, causing the probe
to die.
If the pH probe has been accidentally allowed to dry out;
The pH probe must be ‘hydrated’ for 24 hours in KCl storage solution.

12.0 pH calibration
pH calibration is required before first use to ensure that the first reading is accurate.
•The Bluelab Conductivity/Temperature Probe DOES NOT require calibration.
•The pH of the Guardian Monitor Wi-Fi DOES require calibration.
For accurate pH readings the pH probe is cleaned and recalibrated when:
•The reading is different to what you were expecting.
•The Guardian Monitor Wi-Fi is reset to factory default.
•The pH probe is replaced with a new one.
•It has been a month since the last successful calibration and the calibration indicator
lights are flashing.
When calibrating the pH after first use the pH probe needs to be cleaned. See pH probe
cleaning in section 14.0.
For best pH calibration
pH reading accuracy is dependant on the accuracy and age of the calibration solutions used,
and use and cleanliness of the pH probe tip.
•Ensure the pH probe has been cleaned and rinse the pH probe with clean water between
calibration solutions to reduce contamination of the pH solutions.
•Only fresh uncontaminated solutions should be used.
•Calibrate the pH at the same temperature as the solution to be measured.
•ALWAYS calibrate the pH probe with pH 7.0 then pH 4.0 or pH 10.0.
NOTE: The conductivity/temperature probe does not need to be calibrated, but must be
cleaned to remove any build up of nutrient salts. See Section 13.0.
The pH calibration involves cleaning the pH probe tip and then calibrating in TWO SOLUTIONS.
If a reading below pH 7.0 is expected, use pH 7.0 and pH 4.0 calibration solutions.
If a reading above pH 7.0 is expected, use pH 7.0 and pH 10.0 calibration solutions.
Follow the steps on the following page for Guardian Monitor pH calibration.
Storage and use of calibration solutions

English
10
•Always place the lid back onto the bottle after use or evaporation will occur rendering the
solution useless.
•DO NOT measure directly into the bottle. Tip a small
amount into a clean container and discard after use.
•Never add water to solutions.
•Store in a cool place.
pH reading accuracy is dependant on the accuracy and age of the
calibration solutions used, and use and cleanliness of the pH probe tip.
12.0 pH calibration cont.
To calibrate the pH probe

Successful pH 7 and pH 4
calibration
12.0 pH calibration cont.
The LEDs next to the pH window will let you know the status of calibration. See the table
below.
NOTE: The pH probe and hence calibration will eventually fail due to;
•Contamination and age of pH probe.
•pH probe used to measure solutions at temperatures above 50 °C (122 °F) or below
0 °C (32 °F).
•pH probe exposed to aggressive chemicals.
•Internal damage to the pH probe from rough treatment.
•Damage to the cable of the pH probe from rough treatment.
•pH probe repeatedly drying out.
•Moisture getting inside the BNC connector on the pH probe cable.
pH LEDs
Using factory default calibration values. Both LEDs off. Readings may be
unreliable.
pH 7 calibrated OK. Using factory default for pH 4/10. pH 7 calibrated OK. Using
factory default for pH 4/10. Readings may be unreliable.
pH 7 and pH 4 or pH 10 calibrated OK.
Flashing
30 days passed since last full calibration - calibration due.
Flashing
If 7 is flashing and 4/10 is off, calibration is also required as 4/10 was never
calibrated.

English

13.0 Placement of probes
Both the Bluelab pH Probe and Bluelab Conductivity/Temperature Probe require
submersion in the liquid for a measurement to occur.
•Do not pour concentrated nutrient solution or pH adjuster directly onto probes when in
the reservoir, as very strong acid may damage the probes or your alarms (if set) may
trigger.
Fit the (optional) pH probe holder to the stem of the pH probe
using a gentle twisting motion.
Place the pH probe into the reservoir and push the suction cup
onto the side of the reservoir but far enough down so the pH
probe tip is in the solution. The holder prevents damage to the
pH probe from banging onto the side of the reservoir with
movement of the solution.
Place the conductivity/temperature probe into the reservoir
selected.

English
13
14.0 Set alarms (optional)
The alarm function warns you when the solution
deviates from the desired levels you have chosen
for each measurement.
When an alarm condition is present, the display
of the affected measurement will flash.
If the measurement changes back to within the
limits you have chosen, the flashing will stop.
Even though the resolution of the Guardian is 10 ppm / TDS, the alarms will set only in 50
ppm and 70 ppm increments.
There are two ways to set the alarm, ‘quick-set’ or ‘detailed-set’.
Alarm ‘quick-set’
This allows you to quickly set the ‘alarm HIGH’ and ‘alarm LOW’ values for all of the three
measurements. The table below shows the values that are pre-set when ‘quick-set’ is used.
NOTE: Before you use the quick-set function, the solution in the tank/reservoir must be
adjusted to the desired/actual levels for all three parameters and the levels displayed in
each of the windows. If this is not done you should use the alarm ‘detailed-set’.
To activate the ‘quick-set’ alarm;
Press and hold the alarm button until ‘AL H’ is displayed in
all three windows.
Release the alarm button.
Press the Settings button once.
All three windows will display Auto for
1 second and then SAVE will be displayed in the conductivity
window. The alarms are now auto set and the alarm mode
will be turned on. The alarm LED will glow.

15.0 Cleaning the conductivity/temperature probe
Cleaning the Bluelab Conductivity/Temperature Probe
Periodically cleaning ensures accurate readings.The conductivity/temperature probe is
cleaned using the Bluelab Conductivity Probe Cleaner, or “Jif” a trade name for a liquid
scourer cream used in home bathrooms and kitchens. Never use scented varieties as they
contain oils that contaminate the conductivity/temperature probe.
Remove shroud.
Warm the shroud in your hand for a few seconds
to help with removal.
Clean the conductivity probe face.
Place one or two drops of Bluelab Conductivity
Probe Cleaner onto the probe face and rub with
the Bluelab Chamois or your finger firmly and
vigorously.
Rinse the conductivity probe face.
Rinse off all traces of cleaner under running tap
water while scrubbing the probe face with the
other side of the Bluelab Chamois or the same
finger.
Check that the water forms a smooth film on the
probe face. Ensure you have a clean, smooth film
without any beads of water. If you have beads of
water, repeat steps 2 and 3.
Refit the shroud and test in 2.77 EC Conductivity
Standard Solution to ensure adequate cleaning.
Place the probe tip into the solution, wait for the
reading to stabilize to a constant value. This can
take a few minutes while the probe adjusts to the
temperature of the solution.
Repeat the cleaning process if the reading given is
not within 0.1 EC, 1 CF, 50 ppm or 70 ppm of the
values in the table below.
Testing the Bluelab Conductivity/Temperature Probe
The conductivity/temperature probe is tested in either
2.77EC/27.7CF/1385 ppm or 1940 ppm solution
depending on the unit of conductivity chosen.
Use the standard solutions in the table to the
right. Bluelab solutions are recommended.
NOTE: The shroud MUST be left on the probe when taking readings.

16.0 Cleaning the Bluelab pH Probe
To ensure accurate readings the pH probe tip needs to be rinsed in water after each use
and cleaned prior to calibration using the following instructions.
The storage cap must always be put back on after cleaning. Always ensure it contains
enough Bluelab pH Probe KCl Storage Solution to cover the probe tip.
Remove storage cap from pH probe.
Hold the top of the storage cap, twist the cap to
loosen then remove.
Rinse pH probe tip under fresh tap water.
Never use RO (Reverse Osmosis), Distilled or De-
ionized water.
Fill a small plastic container with clean tap water.
Add a small amount of Bluelab pH Probe Cleaner
or mild detergent (dishwashing liquid).
Gently stir the probe tip in the mixture.
Ensure that you do not ‘knock’ the soil pH probe
on the side of the container as this may cause
damage to the probe.
If the probe tip 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 tap water to
remove all traces of the detergent mixture.
Calibrate pH probe after cleaning, see section
12.0.After calibration, store pH probe in the
storage cap, ensuring there is enough KCl Storage
Solution to cover the probe tip.

English
17
17.0 Hydrating the pH probe
Hydrate the pH probe in Bluelab pH Probe KCl Storage Solution when:
•the probe tip has not always been stored in KCl storage solution, to improve the
reading response speed.
•
the probe tip has been accidentally allowed to dry out.
Never use RO (Reverse Osmosis), De-ionized or Distilled water. Pure water changes the
chemistry in the reference, causing the probe to die.
Loosen, then remove the storage cap. Place the pH
probe upright in a plastic container.
Bluelab pH
Probe KCI
Storage Solution
Clean the pH probe tip. Ensure the probe tip is
cleaned before hydrating. See section 16.0 for
instructions.
