1.0Introduction
English
The Bluelab Soil pH Meter has two press buttons; ‘calibrate’ and power. The power button
requires a short press; release in about one second. The ‘calibrate’ button requires a long
press; hold for at least three seconds and release when the display starts flashing.
Turning the soil pH meter on and off
1
A short press of the power button will turn the soil pH meter on. The soil pH meter
automatically turns off after approximately four minutes if no buttons are pressed.
If the soil pH meter turns off before the reading is taken, short press the power
button to turn the soil pH meter on again.
2.0 Preparing for use
The following tasks must be performed before the Bluelab pH Meter is used for the
first time.
1
Insert batteries.
See section 8.0.
2
Connect soil pH probe
Connect the soil pH probe to the soil pH meter
by lining up the lugs of the BNC fittings. Fasten
securely by pushing the pH probe connector on
and twisting one quarter turn.
3
Remove the storage cap
Remove the pH probe storage cap by gripping
the top of the cap and gently twisting the base
one rotation clockwise to loosen slightly. Next
slowly slide the cap off the pH probe. DO NOT
completely remove the base of the cap from the
top of the cap.
CAUTION: When the soil pH probe is not in use,
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.

3.0
Calibration
English
pH calibration is required before first use and then monthly to ensure readings are
accurate.
For accurate pH readings the soil pH probe is cleaned and recalibrated when:
•The reading is different to what you were expecting.
•The batteries have been removed or changed.
•The soil pH probe is replaced with a new one or is disconnected from the soil pH Meter.
•The pH calibration indicators have disappeared.
When calibrating the pH after first use the soil pH probe needs to be cleaned. See soil
pH probe cleaning in section 8.0. The soil pH probe does not need to be cleaned for
initial calibration.
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 soil pH probe tip.
• Ensure the soil pH probe has been cleaned and rinse the soil pH probe tip 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 soil pH probe with pH 7.0 then pH 4.0 or pH 10.0.
The pH calibration involves cleaning the soil 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 below for soil pH meter calibration.
Storage and use of calibration solutions
•Always place the lid back onto the bottle after use or evaporation will occur rendering
the solution useless.
•Store in a cool place.
•DO NOT measure directly into the bottle. Tip a small amount into a clean container
and discard after use.
•Never add water to solutions.
pH reading accuracy is dependant on the
accuracy and age of the calibration solutions
used, and use and cleanliness of the soil pH
probe tip.

4.0 Information about measuring the pH of soils/media
English
pH is the measurement of the hydrogen ion concentration (H+) - acidity and
its opposite, alkalinity. Neutral pH is 7.0 pH. Acidity measures below seven
pH (7.0 pH) with alkalinity measuring above it (7.0 pH). See chart below.
In soils or growing media, pH strongly influences the availability of nutrients and the
presence of microorganisms in the soil.
Certain plants require a particular pH range to enable the required nutrients to be consistently
available to the plant. If the solution is too acidic or too alkaline it can cause “lock up” – a
situation which restricts certain elements essential for growth from being absorbed by the
root structure. This in turn reduces plant health and performance. Deficiencies in the required
elements become apparent in plant growth and can lead to crop failure.
Low soil pH causes aluminium and manganese toxicity in plants and reduces the availability
of soil phosphorus. High soil pH also reduces soil phosphorus availability and reduces micro
nutrients such as zinc and boron to plants.
The chart below shows how nutrient pH levels influence the uptake of certain elements.

4.0 Information about measuring the pH of soils/media cont.
English
Taking pH measurements of soils with an electronic meter is indicative
rather than absolute.
The following factors are outside the control of any soil pH meter, so to minimise
their effect on the accuracy of the pH measurement you should consider the
following precautions:
Moisture level/raw water
If the sample you are wishing to measure is dry, add RO water or distilled water to
moisten. Ideally wait 24 hours before you take a measurement.
NOTE: If you add tap water, you will influence the soil pH reading based on the pH of the
tap water.
Calibration of the soil pH meter and cleanliness of the soil pH probe tip
Calibrating the soil pH meter at least monthly will ensure accurate readings. Cleaning the
soil residue from the probe tip and storing the soil pH meter in a clean moist state will
provide reliable readings as well as prolonging the probes life.
Sample selection
For field testing, remove the top 5 - 10 cm / 2 - 4” of the top of the soil. Samples are
taken approximately 15 - 20 cm / 6 - 8” down into the substrate and from various areas,
then an average of the readings is used.
For container grown plants, it is recommended to check the pH level of the substrate
prior to planting.
Factors affecting pH in the soil or media:
Soil type
Soils formed under high rainfall conditions (e.g. Eastern USA) are more acidic than those
formed under dry conditions (e.g. Western USA).
Growth stage of the plant
Uptake and requirements of particular elements change as the plant progresses through
it’s growing cycle. Recording pH level data to create a history is valuable.
Applications and types of fertilizers
Applications and types of fertilizers can alter the pH level significantly. The time at which
you take the reading is important. Evaluate the brand of fertilizer to see if it is altering the
pH in the wrong direction.
Applications of sprays
As sprays can soak into the soil/media, a change to the pH level could result.
Soil/media temperature
High temperature soils may have a high concentration of CO2. The higher the
concentration of carbon dioxide pressure results in more carbonic acid which lowers pH.
7
pH range for soil crops
The recommended pH range for soil crops is 6.2 - 7.2, but this is plant specific.
5.0 Measuring the pH value
English
Once the Bluelab Soil pH Meter has been set up and calibrated, using it to measure a pH value
involves using the Bluelab Soil pH Probe, the green dibber/auger, a soil/media sample and
button functions. NOTE: The soil pH probe tip must not have dried out. If it has dried, soak the soil
pH probe in tap water for one hour prior to taking a measurement.
1
Remove the top 5 cm / 2 in. from the surface of the sample area.
2
Insert the dibber/auger into the sample to a depth of about 20 cm / 8 in. and remove.
3
If the soil/media is dry, moisten with a small amount of distilled water.
Remove the storage cap and insert the soil pH probe to the same depth ensuring the
probe end makes proper contact with the soil.
Turn the soil pH meter on.
Wait for the reading displayed on the soil pH meter to stablize to a constant value. This
can take up to four minutes. Record the reading.
Remove the soil pH probe from the soil/media and wash the soil pH probe tip under fresh
running water (not distilled) to remove any remaining soil residue.
Repeat the procedure in different locations and take the average of the measured data as
the pH level is representative of the sample area.
If the soil pH meter turns off while taking a measurement, simply press the power button
to turn the soil pH meter back on and continue with your measurement.
Store the soil pH probe between measurements. See section 10.0.

The greatest source of error in soil analysis comes during sample collection. An effort should be
made to ensure each sample properly represents the area being sampled.
• The readings taken with this method could be higher than those taken by other methods
• Consistency of the method used is important to be able to compare sets of results
• The accuracy of this method cannot be guaranteed because of the variables involved
• The results should be viewed as ‘indicative’ rather than ‘absolute’
Collection of sample
1 Sample in a zig-zag pattern across the required area.
2 Remove 15 mm / 5/8 in. of top soil before sampling at a depth of 150 mm / 6 in.
3 Mix all collected samples together thoroughly.
4 Allow to dry in the air or in an oven at 40 °C / 104 °F.
5 Weigh out 20 g / 0.7 oz of the collected soil into a 150 ml / 5 fl oz plastic sample jar.
Sample preparation
1 Add 100 ml / 3 fl oz of distilled or deionised water, screw lid on tightly.
2 Shake continuously for 5 minutes. Leave overnight and shake again the next morning.
3 Allow to settle for 15 minutes after shaking and strain sample into clean measuring cup.
Take pH readings as follows:
1 Remove the storage cap and insert the soil pH probe tip into the soil solution sample.
2 Turn the soil pH meter on.
3 Wait for the reading displayed on the soil pH meter to stablize to a constant value. This
can take up to four minutes. Record the reading.
4 Remove the soil pH probe from the soil solution and wash the soil pH probe tip under
fresh running water (not distilled) to remove any possible soil residue.
5 If the soil pH meter turns off while taking a measurement, simply press the power button
to turn the soil pH meter back on and continue with your measurement.
Store soil pH probe between measurements
