1.0 Introduction
The Palintest Pooltest 9 Bluetooth is a direct-
reading, waterproof photometer for determining
key water quality parameters for swimming pools,
hydrotherapy pools, hot tubs and spas. Designed
for both portable and static use, the Pooltest 9
Bluetooth should always be used with genuine
Palintest reagents for optimal performance.
The fundamental operating technique applied to
the Pooltest 9 Bluetooth is based on the principles
of optical absorbance and scattering of visible light.
Optical absorbance techniques are based on the
use of Palintest (spectro)photometric reagents,
creating visible colours with specific analytes
upon reaction. The intensity of colour produced is
measured with the Pooltest 9 Bluetooth and the
data compared to the stored calibration data to
deliver the final result.
Optical scattering techniques produce small
particles to scatter the source beam, the amount
of scatter providing a result for the concentration
of parameter under test.
or more information regarding the science behind
both photometric and turbidimetric analysis
technology please visit www.palintest.com/know.
The Pooltest 9 Bluetooth is provided with
programmed methods for a comprehensive range
of water quality parameters. Upon choosing a test
the instrument automatically selects the required
parameters for accurate analysis including
wavelength and reaction time. On completion of
some tests optional follow-on tests are available
plus results can be converted to alternative units
of expression e.g. mg/l to ppm, N or NH3.
The Pooltest 9 Bluetooth offers a choice
of connectivity to download all or selected
results via Bluetooth 4.0 wireless connectivity
or USB connection.
Bluetooth 4.0 (also known as Bluetooth SMART
or Low Energy) connection allows seamless
data exchange using the Palintest Aqua Pal
app, available for iOS and Android devices.
See Appendix 5 for more details.
USB connection via the port located at the rear
of the instrument provides a choice of either
‘Hard Disk’ mode or serial communication mode.
See Section 6.5 for more details.
The Pooltest 9 Bluetooth offers a choice of
either mains power via the USB port or using
three 1.5V ‘AA’ batteries (supplied).
The Pooltest 9 Bluetooth is delivered with
a two year warranty and a full range of service,
calibration and technical support. Additional
resources are available at www.palintest.com
relating to both products and applications.

3Taking a Sample
6
3.0 Taking a Sample
The first critical step in any analysis is taking a
representative sample. When selecting a sample
point a number of care points are recommended
as follows:
• Ensure the sample point is safe to access
and follow all relevant/required precautions
• When sampling from a tap or outlet, remove
any attachment and clean the tap/outlet with
a dry cloth before allowing to run for 1 minute
prior to sample collection
• When sampling from a pool or spa take the
sample as near as possible to the centre of
the pool and at least 20cm below the surface
of the water
• Rinse any sample container repeatedly with
the sample to prevent any cross contamination
from previous samples
• Once collected the sample must be processed
immediately or as quickly as possible, especially
for highly reactive species such as chlorine for
example. The use of a portable field test kit
makes this possible. However if the delay
between sample collection and analysis is likely
to be several hours chill the sample to preserve
and prevent potential sample deterioration
• Samples containing solid particles can interfere
with photometric analysis. Either allow solids
to settle and decant the clear liquid or filter
the sample prior to analysis

Analysing Samples
6.0 Analysing Samples
The Pooltest 9 Bluetooth provides simple,
accurate and reliable analysis of key pool, spa
and other aquatic samples. Selecting the required
parameter and performing the test are supported
through on-screen prompts and comprehensive
test instructions.
The principle of photometric testing is based on the
absorption or scattering of a measured intensity
of incident light compared to the light intensity
reaching the detector array. The light intensity is
determined as Transmittance (%T) or Absorbance
(A) and compared to calibration tables stored within
the Pooltest 9 Bluetooth. The stored calibration
tables convert %T or A to results in a variety of
units (mg/l, ppm etc.) as defined in Section 6.6.
Calibration tables are defined by Palintest based
on the measurement of reference standards using
Palintest reagents. To achieve the best quality
results there are a small number of care points:
1Always use the provided light cap to prevent
ambient light affecting the results.
2Ensure Sample and Blank cuvettes are clean, dry
and inserted correctly into the sample chamber,
using the allocated orientation mark to align.
3Always blank the instrument with untreated
sample prior to analysis.
Additional guidance is provided in Appendix 1
Photometric Testing Hints and Tips
6.1 Selecting Test Parameters
The Pooltest 9 Bluetooth offers a number
of choices to select the parameter to test:
Test Number Entry - use the numeric keypad
to enter the unique Test Number to directly
access any programmed calibration.
Direct Entry - use the numeric keypad to
directly access the 10 most common tests with
a single key push.
Choose a Test - the full list of test parameters is
available by selecting Choose a Test and scrolling
using the up/down keys. When the desired parameter
is highlighted, press the OK key to access the
method. Tests are presented in Test Number order.
When the required test is selected the Pooltest 9
Bluetooth automatically selects the correct wavelength
and sets additional method parameters as required.
Test method protocols are defined in detail section 8,
including the reagents and accessories that may
be required.
When a test is selected, the Pooltest 9 Bluetooth
will display a number of screens and options to
guide the user through the testing process, as
described in the following pages.
6.2 Dilution Factor
If selected in the System menu, the initial screen will
request the defined Dilution actor to apply to results.
If Dilution actor is not active this screen will not
be shown.
Results shown on the final screen have automatically
been corrected for dilution prior to display.
Corrected results will also be stored in the log.
Note: if the System Lock is applied the Dilution
actor functionality cannot be switched on or off
from the current status until the system is unlocked.
6.3 Blanking the Pooltest 9 Bluetooth
Blanking the photometer is a key first step in
photometric analysis, effectively removing the
potential entrained sample colour and minor amounts
of turbidity from calculation of analytical results.
To blank the photometer, prepare a Blank cuvette
using untreated sample i.e. sample that has not
been reacted with any reagents. If the sample is
to be diluted or physically treated (filtered for
example) before analysis, use the same dilution/
treatment for the Blank cuvette.
Pooltest9Bl etooth_ZI INST 7009B EN 29/7/15 12:03 Page 15

6Analysing Samples
16
When accessing the test method the Pooltest 9
Bluetooth will request the user to Insert Blank.
Insert the Blank cuvette and press OK.
The Pooltest 9 Bluetooth will determine the
absorbance due to the sample colour at all
wavelengths simultaneously and store in
temporary memory for use in analysis.
Upon successful blanking the Pooltest 9
Bluetooth will automatically move to the Insert
sample stage of the analytical method.
If the sample is too highly coloured to support
effective blanking and subsequent analysis the error
message “Error 9 is caused by the blank cuvette being
too dark. Check the correct cuvette is being used”.
Ensure the blank cuvette is being used, not the
sample plus reagent cuvette. Sample colour can
be reduced by dilution with clean water; the
dilution selected should take account of the
expected concentration of parameter under test.
Blank results are stored in the temporary memory
of the Pooltest 9 Bluetooth and will be used for
all subsequent tests until:
• The instrument is powered down (temporary
memory is lost/deleted)
• A new Blank reading is taken - this option is
available on accessing any subsequent test at
the base of the screen. Repeat the blanking
process if the sample changes significantly
or a new sample is under test
• Some tests use a reversed blanking process
where a coloured blank cuvette may be required.
When changing between standard tests and
‘reverse blank’ test, a new blank will be
requested by the Pooltest 9 Bluetooth.
If the blank value generated in this step is not
detectable an error message will be displayed
“Error 7 is caused by too much ambient light. Try
using the light cover provided with the instrument”.
See Appendix 1 Photometric Testing Hints and
Tips for more advice regarding effective blanking.
6.4 Reading Results with
the Pooltest 9 Bluetooth
Assuming a suitable blank has been recorded,
the next step of the photometric analysis process
is to carry out the reading step.
Prepare a Sample cuvette following the method
instructions provided in Chapter 8.

Press OK to begin the measurement process.
The screen will display Reading...
At the completion of the measurement process
the result is displayed on screen.
6.5 Timer
Many photometric methods require a reaction time
to develop, the recommended time period being
documented in the Palintest Phot
Book and included
as part of the method parameters programmed into
the Pooltest 9 Bluetooth.
Tests requiring a reaction time will have the option
to select an automatic timer to count down the
reaction time required. While in the Insert sample
screen use the right key to move the cursor to
highlight Timer.
The programmed reaction time will be displayed.
Press OK to Start the countdown.
Three options will be displayed:
Stop cancel the countdown timer
Exit exits the countdown screen and
returns to the Insert sample
screen. The countdown will
continue and the current time can
be seen by selecting Timer.At the
end of the countdown an audible
alarm will sound to indicate the
sample is ready to read. Select
OK to read the sample manually.
Exit and Read exits the countdown screen and
automatically reads the sample
at the completion of the allocated
time period.
6.6 Changing Result Units of Expression
Many chemical species have a number of
alternative units that can be used for reporting
results e.g. Phosphate can be expressed as PO4
or P for example.

Where alternative units of expression for results
are available the ▲▼ symbols will be displayed
next to the current result units. Use the up/down
arrows to change the units of expression as
required. Values are modified automatically.
Results stored in the log will be in the units
selected on screen, changing the chemical species
will add an entry to the log showing the updated
result and species parameter selected.
6.7 Follow-on Tests
A number of photometric methods have additional
optional methods that can be applied, known as
ollow-on Tests e.g. Phot 008 Total Chlorine follows
Phot 007 ree Chlorine. ollow-on methods are
usually either based on further reagent addition to
the sample just measured for sequential parameters
or used to correct for potential/known interferences.
ollow-on tests are clearly defined in the Section 8
and, if available, are accessed via the Follow-on
option located at the right hand side of the options.
To access the ollow-on test, highlight ollow-on
and press OK. The next method is automatically
loaded and operated in the usual manner.
NOTE: if no viable result is produced during
the first stage of a sequential test method, the
ollow-on option will be automatically removed.

The Pooltest 9 Bluetooth provides simple test
protocols for the key parameters required to
effectively control swimming pools, hydrotherapy
pools, spas and hot tubs.
The tests available by number are as follows:
Test 1 Chlorine-Free/5 or Chlorine-Free/10
Standard Range: 0-5.00mg/l (ppm) Cl2(use DPD 1)
Extended Range: 0-10.0mg/l (ppm) Cl2(use DPD X )
Colour change: Colourless - Purple/Red
1Rinse test cuvette with sample leaving
two or three drops in the tube.
2Add one DPD 1 or DPD XF tablet, crush
tablet and then fill the test tube with
sample to the 10ml mark. Mix to dissolve
tablet fully and ensure no particles remain.
3Take photometer reading immediately.
The result may drift on standing.
4Retain test solution if the Total
Chlorine ollow-On Test is required.
Test 2 Chlorine-Total/5 or Chlorine-Total/10
Standard Range: 0-5.00mg/l (ppm) Cl2(use DPD 3)
Extended Range: 0-10.0mg/l (ppm) Cl2(use DPD XT)
Colour change: Purple/Red from Test 1
increases in intensity
Carry out this test on the solution
remaining from the ree-Chlorine/5 test.
1If any shock treatment chemicals have
been added to the pool, add one DPD
Oxystop tablet, crush and mix to dissolve.
Stand for one minute before proceeding.
This will prevent a false response caused
by the shock treatment chemicals.
2Add one DPD 3 or DPD XT
tablet, crush and mix to dissolve.
3 Stand for two minutes
to allow full colour development.
4Take photometer reading
after two minutes have elapsed.
Note: To obtain Combined Chlorine
residual subtract ree Chlorine result
from Total Chlorine result:
Combined Chlorine =
Total Chlorine - Free Chlorine

Test 3 Bromine
Range: 0-10.0mg/l (ppm) Br2
Colour change: Colourless - Purple/Red
1Rinse test cuvette with sample leaving
two to three drops in the tube.
2Add one DPD 1 tablet, crush tablet and then fill
with sample to the 10ml mark. Mix to dissolve
tablet fully and ensure no particles remain.
3Take photometer reading immediately.
Result may drift on standing.
Test 4 Ozone
Range: 0-2.00mg/l (ppm) O3
Colour change: Colourless - Purple/Red
1Rinse test cuvette with sample leaving
two to three drops in the tube.
2Add one DPD 4 tablet, crush tablet and then fill
with sample to the 10ml mark. Mix to dissolve
tablet fully and ensure no particles remain.
3Take photometer reading immediately.
Result may drift on standing.
Note: The ozone test also responds to chlorine
and bromine. Pools using ‘ozone with chlorine’
treatment systems, or other combined treatments
will produce a result at this stage representing the
ozone plus other treatment chemicals. To determine
ozone specifically requires an additional protocol
as follows:
Correction for Chlorine or Bromine
1ill a test cuvette with sample to the 10ml
mark. Add one DPD Glycine tablet, crush
and mix to dissolve.
2Take a second clean test tube and add two to
three drops of solution from the first tube.Add
one DPD 4 tablet, crush and then make up to
the 10ml mark with the solution from Step 1.
Mix to dissolve tablet fully.
3Take Photometer reading immediately. The
DPD Glycine complexes ozone in the sample
and the result displayed equates to chlorine
or bromine present in the sample only.
4Subtract the result obtained in Step 3 from
the initial result to determine the ozone
concentration specifically.
Test 5 Copper-Total/5
Range: 0-5.00mg/l (ppm) Cu
Colour change: Colourless - Purple
1ill test cuvette with sample to the 10ml mark.
2Add one Coppercol No 1 tablet and one
Coppercol No 2 tablet, crush and mix to dissolve.
3Take photometer reading.
Test 6 pH-Phenol Red
Range: pH 6.5-8.5
Colour change: Yellow - Red
1ill test cuvette with sample to the 10ml mark.
2Add one Phenol Red tablet, crush
and mix to dissolve completely.
3Take photometer reading.
Test 7 Total Alkalinity
Range: 0-500mg/l (ppm) CaCO3
Colour change: Yellow - Green - Blue
1ill test cuvette with sample to the 10ml mark.
2Add one Alkaphot™ tablet, crush
thoroughly and mix. Ensure all particles
have dissolved completely.
3Allow to stand for one minute.
4Take photometer reading.
Note: If a thin yellow layer is observed at the
bottom of the tube, the cuvette should be
thoroughly remixed before measurement.
