pH indicator paper
Our pH indicator papers are made from the highest quality filter papers which are
impregnated with indicators, dried and then cut to size. We generally supply these as books
or reels and pack them to ensure they are protected against all major external factors e.g.
moisture, light, gases and vapours.
pH indicator strips (non-bleed)
Our pH indicator strips are impregnated with indicators which have been prepared as a non
bleed system therefore the resultant colour remains far longer and readable until the pad is
dry and without contaminating the test solution. This special method of manufacturing give
the pH indicator strips particular advantages over the pH indicator papers.
packaging sizes
The standard packaging for our pH indicator papers is a pack of 10 books with each book
having 20 strips; or in lengths of 5 metres as a reel. We are also able to supply pH indicator
papers in other presentations and sizes upon special request of the customer.
shelf-life and storage
Our pH indicator papers and strips can be used for up to 3 years when stored at temperatures
up to 25oC, protected from light and in dry conditions. The pack must be immediately closed
after removing each indicator paper or strip.

an introduction to pH
pH
is the measure for the concentration of the hydrogen ion. This is chemically defined as the negative
decimal logarithm of the hydrogen ion activity in a solution. Pure (neutral) water has a hydrogen ion
activity of 10-7 at 25oC, which corresponds to a pH of 7.
The pH range extends from pH 0 to pH 14. The more H+ ions the solution contains (acids) the lower the
pH (<7), while the fewer the H+ ions and therefore more OH- ions (bases) the solution contains, the more
alkaline it is and the higher the pH (>7).
pH follows a logarithmic curve where each stage of the pH scale follows a ten fold multiplication.
factors influencing pH
pH indicators can be regarded as weak acids or bases therefore the degree of dissociation can be influenced by co-solvents such as
salts, proteins, colloids and organic solvents. Temperature is also a key factor which can influence pH and must be considered when
conducting any testing. When carrying out tests using pH indicators, a variety of errors can occur:
the indicator acid-base error
The indicator error can occur as a
result of the acid or base nature of
the indicator dye and occurs only in
solutions that are not or inadequately
buffered. If the buffering capacity of
the solution is low e.g. tap water, river
water, distilled water, strongly diluted
salt solutions, the pH value can deviate
up to one whole pH unit in extreme
cases. That being said, the quantity
of indicator in a test strip is usually in
the range of micrograms therefore the
effect is almost non-existent unlike
liquid indicators where the effect may
be more pronounced resulting in an
erroneous reading.
6
the salt error
The salt error depends on the
concentration and the type of salts
present in solution as they produce a
shift in the equilibrium of the indicator.
This can mean that errors can occur
in a number of salt solutions. Where
the salt concentration is less than 2
mol/L, correction of the result is not
normally necessary. The salt error is
specific for each indicator depending
on its structure and charge. Hence, in
the presence of foreign neutral salts,
the end point of the indicator acid is
moved towards a higher hydrogen ion
concentration i.e. towards a lower pH
value, while that of the indicator bases
is moved towards a lower hydrogen ion
concentration i.e. towards a higher pH
value.
the protein error
The protein error occurs as a result of
any proteins present that bind to the
indicator acids due to their amphoteric
character. The basic groups of proteins
in solution bind to the indicator acid
and the acidic groups of proteins in
solution bind to the indicator bases.
The protein error effect depends on
the type of protein, its quantity and the
type of indicator itself. The simpler its
structure, the lower the interference
with the pH measurement. However
the protein error can be exploited and
used to measure the protein content in
solutions.
the pH test
The importance of pH exerts its effect in various chemical processes especially within biochemistry and chemistry. Many analytical
methods and tests are often influenced by the pH which is where it is of more practical importance than just determining the
concentration of other ions. pH can be measured using pH indicator papers and strips.
pH indicator papers and strips can be used directly when required without the need of any accessories or any pretreatment. Results
are immediate and can be in full pH intervals or down to 0.2 pH intervals. The results are highly accurate which allows the user to
take the necessary measures no matter which field of the industry or environmental sector these pH test are being used in.
The benefits of using pH indicator papers and strips must be assessed on the measurement method, its application and the
requirements. pH can rapidly change due to chemical, physical or biological processes therefore making it difficult to stabilise.
Our Johnson Test Ppers products and their colour charts have been extensively checked and calibrated using certified buffer
solutions, ensuring that a high quality standards are achieved.
Testing turbid or colour solutions
When the solutions being tested are turbid, coloured or contain a precipitate, then it is advisable to use our pH papers. Take a drop
of the sample solution and allow it to fall on the pH paper. Then compare the colour produced on the reverse side of the paper with
the colour chart, making sure to read the colour produced from the centre of the drop and not the edges.
the alcohol error
The alcohol error occurs in solutions
containing an organic solvent, for
example alcohol, in addition to water.
The addition of an organic solvent to an
aqueous system results in a shift in its
acid base equilibrium. This shift is often
amplified as the alcohol concentration
increases, shifting the pH measurement
by up to 1 pH unit.
the alkaloid error
This type of error occurs due to the
formation of deposition complexes
similar to those found with the protein
error.
the temperature error
This type of error is caused by changes
to the ionic product of the water
due to changes in the temperature.
This will reflect upon the pH value
obtained during any measurement. The
temperature error can be felt especially
in hot conditions as our pH papers and
strips have been calibrated and tested
at 20oC.

Universal Indicator Strips
pH 0 - 14 (non-bleed)
The pads on these environmentally friendly strips are prepared as a non bleed system therefore the resultant colour change
remains far longer and readable until the pad is dry.
Each strip is long enough to protect the user from the test solution as the test pads are at the extreme end of the strip.
For accurate pH readings, these strips use 3 different indicator pads and the colours on the enclosed colour chart match the colour
and position of each pad on the strip. This allows these strips to provide a rapid method of measuring the pH of a solution while
producing high quality results each time.
Strips with the non-bleed system provide precise pH values as the different colours
do not mix at the point of testing.
Universal Indicator Strips are also available as single pad strips where it is not
essential to have the high level of accuracy achieved using the 3 pad strips (Product
Codes: 101.3/101.3C). These strips still provide the benefits of using pH indicator
strips along with immediate colour changes and a non bleed system to identify the
resultant pH.

Chlorine Indicator Strips
This test allows a quick and easy method to determine the free/available chlorine in solution.
Chlorine is often seen for use in swimming pools and water supply systems. At the right concentrations it can safely be used to
prevent the growth of harmful microorganisms and remove impurities. Regular checks are required to ensure that the correct
levels of chlorine are being maintained.
In water chlorine occurs as either free chlorine or bound chlorine; the combination of which is total chlorine.
For the determination of chlorine in swimming pools, we recommend the use of our Swimming Pool Indicator Strips (page 20).
