Kemio Test Instructions
Kemio is a multiparameter instrument with three variants.
Kemio Disinfection can test for chlorine, chlorine dioxide, chlorite and
peracetic acid. Kemio Heavy Metals can test for lead, cadmium and copper.
Kemio Multi can test for all of these.
These instructions explain the methodology and care points in detail for each
of these test types.
General Guidelines
· Do not touch the sensor surface.
· Keep the instrument clean and dry during use.
· Keep the instrument on a level surface free from vibrations.
· Sensors perform within a specified temperature range. If the sample
temperature is outside of the specified temperature range for the sensor, the
measurement will proceed as normal but a note will be attached to the test
result.
· For optimum performance we recomend sensors are stored at < 4° C (39° F) for
over one year and < 20° C (68° F) for less than one year.

Free Chlorine, Total Chlorine, and ‘Free and Total Cl’ Tests
9
Palintest’s chlorine sensors can be used to measure free and total chlorine
simultaneously. On Kemio, select either free chlorine or total chlorine to
display a single result, or “free & total” to measure and display both
parameters.
When using labels with the free and total test, labels set for both free
chlorine and total chlorine are listed. The selected label limits apply only
to the parameter they were set for in the configuration menu.
Four different sensor types can be used to measure chlorine:
CLO sensors are used for lower concentrations of chlorine. · 0.02 mg/L – 10
mg/L of free chlorine · 0.02 mg/L – 75 mg/L of total chlorine
CHR sensors are used for higher concentrations of chlorine at higher
temperatures · 0.1 mg/L – 25 mg/L of free chlorine (5 °C – 25 °C) · 1 mg/L –
500 mg/L of total chlorine (5 °C – 30 °C)
CLT sensors are used for higher concentrations of chlorine at lower
temperatures (2 °C – 15 °C) · 0.1 mg/L – 25 mg/L of free chlorine · 1 mg/L –
500 mg/L of total chlorine
FHR sensors are used for high range free only chlorine · 0.1 mg/L – 100 mg/L
of free chlorine (2 °C – 20 °C)
Care Points
If chlorine dioxide is present in solution, it may interfere with the chlorine
reading. Use the degassing step from the chlorite test to produce a chlorine
dioxide-free solution. Ensure the vessel is washed with water between each
test.
10
Results
Free chlorine and total chlorine tests display one parameter each. The free
and total test result screen displays both results. The data log stores one
entry for each test, requiring twice as much space in memory.
The chlorine test methods display the concentration of free and total chlorine
in units of mg/L or ppm Cl-.

sensors for concentrations of peracetic acid ranging from 5 mg/L to 2000 mg/L.
Two sensor types can be used to measure peracetic acid:
PAA sensors are used for higher concentrations. · 10 mg/L – 2000 mg/L of
peracetic acid
PAL sensors are used for lower concentrations. · 0.02 mg/L – 50 mg/L of
peracetic acid
Care Points
Hydrogen peroxide is found in solution with peracetic acid. Palintest’s PAA
and PAL sensors are not strongly affected by the presence of hydrogen
peroxide.
Certain fungicides are known to interfere with the PAA sensor. Contact your
Palintest representative when measuring water samples with fungicides.
Results
The peracetic acid test method displays the concentration of peracetic acid in
units of mg/L or ppm PAA.

214337
Chlorite Test
24
The chlorite test method involves three separate measurements of various
chemical combinations in the sample, followed by some calculations to
determine the total chlorite concentration. The test procedure must be
followed carefully to ensure the chemical reactions and measurements occur
correctly.
A chlorine dioxide measurement forms a part of the chlorite test. However, in
the chlorite test type, only labels and limits for chlorite can be selected.
Care Points
· The chlorite test uses three CDX sensors. These must all be from the same
batch of sensors. If sensors from different batches are used, it may produce
inaccurate results. · If there is chlorine present in the sample, use glycine
reagent during the first CDX measurement. If there is no chlorine present,
skip the glycine step on p. 20. · Chlorine dioxide is a volatile chemical that
leaves a sample very easily. Perform the first test quickly after taking a
sample for an accurate measurement. Do not agitate the sample. · If the
chlorite test method is interrupted, or if an error occurs partway through the
test procedure, the entire test must restart from the beginning to ensure
accurate results. · Use separate vessels for the first CDX test before the
degassing step, and the second and third tests with CR-1 and CR-2. Do not mix
up the two vessels. · Do not let the kit stay wet. Trapped humidity could
damage the kit components.
25
Results
The chlorite results screen displays two readings: the calculated chlorite
result and the chlorine dioxide result measured by the first sensor.
The chlorite test method displays the concentration of chlorine dioxide in
units of mg/L or ppm ClO2, and the concentration of chlorite in units of mg/L
or ppm ClO2-.

Metals Tests
34
(Lead, Cadmium, Copper, Arsenic)
The following metal sensors are available for use with Kemio Heavy Metals and Kemio Multi.
Metal Lead Cadmium Copper Arsenic
Sensor Type MPB MCD MCU MAS
Range 1 – 100 µg/L (or ppb) 0.5 – 10 µg/L (or ppb) 0.1 – 2.0 mg/L (or ppm) 2.0 – 250 µg/L (or ppb)
Care Points
· Lead, Cadmium and Copper sensors contain a very small amount of mercury.
Check your local laws for disposal. In most regions there are no special
requirements. In some regions the capped disposable vessel must be disposed of
per regional laws.
· Avoid touching the chemicals on the sensor surface. · Avoid cross-
contamination between samples ensuring all
equipment used is clean. · Ensure the Soluprep tablets are completely
dissolved before
starting the test.
Results
The lead, cadmium and copper results screens display a single reading, in
units of µg/L or ppb Pb, Cd or Cu. Separate Arsenic tests are available for
either Total Arsenic or Arsenic (III). Selecting, Speciated Arsenic will
provide results for Total Arsenic, Arsenic (III) and Arsenic (V) in units of

Arsenic Testing Critical Care Points
44
4
3
2
1
If the sample is turbid (cloudy) then it will need to be filtered to avoid
blocking of the ion exchange cartridge. This can be done simply by inserting a
particulate filter to the syringe in front of the ion exchange cartridge.
Samples that have been
acidified must be neutralized
before analysis. Acceptable
pH
range is pH 4 – 7.
Ensure that sample is within
10°C
35°C the temperature range
10°C – 35°C.
Always store the ion exchange cartridge in the tube it is supplied in.
45
Darkening of the inlet end of the ion exchange cartridge is normal with some
types of water. If this color extends the entire length of the filter then it
should be discarded.
Speciated Arsenic requires two sensors to be used during the test procedure.
For valid results, these two sensors must have the same batch number.
Check and adhere to all local regulations regarding the disposal of the sensors, ion exchange cartridge and sample water.
46

Results
At the end of the countdown, the test results will display on screen. The
number of results displayed depends on the test type.
Disinfection test results are displayed in mg/L or ppm. Metals tests results
are displayed in µg/L or ppb.
Dilution
If a label with a dilution factor was used during the test, the factor will
have applied to the number on screen. For example, if a 50mg/L solution was
diluted 5X and measured by Kemio using a label with a 5X dilution factor, the
result displayed on the screen will be 50mg/L.
It is critical that the correct dilution is performed when a label with a
dilution factor is used.
47
No Limits
If no label or a label with no limits was used during testing, the page title
will be DETAILS on a blue background.
Limits
If a label with limits was used, either a green PASS or a red FAIL will be
displayed at the top of the screen. This is simple traffic light system
enables a quick and clear decision by the operator.
