produces results on-site, within minutes that are accurate and
comparable to expensive laboratory tests. It measures the
electrochemical reaction of a weighted sample placed in an extraction
liquid. It automatically shows a temperature compensated reading of
percent of chlorides on its digital display. A wide range - from 0.002
to 2% chloride by weight - is covered.
Chlorimeter Extraction Liquids
determination of the chloride ion concentration in concrete is
essential in assessing the need for maintenance on, for example, bridge
decks and parking structures. The test can also be used to ensure that
materials used in new construction are free from potentially harmful
chloride ion levels.
With this method, the concentration
of acid soluble chlorides is measured. In most cases, this
is equivalent to total chloride concentration.
sample of powder is obtained
by drilling and careful quartering. Then an accurately weighed 3 gr.
(0.1 oz) sample is dissolved in 20 ml (0.67 fl. oz.) of extraction
liquid which consists of a precise, measured
concentration of acid. For sampling wet concrete
a 3 gr. (0.1 oz.) sample of mortar (i.e. without coarse aggregate) is
used. Typically for concrete, samples that are to be analyzed
for chloride are obtained at various depths, thereby supplying the
engineer with a chloride ion profile.
chloride ions react with the acid of the extraction liquid in an
reaction. An electrode, with integral temperature sensor, is inserted
into the liquid and the electrochemical reaction measured.
designed instrument converts the voltage generated by the chloride
concentration and sensor into a reading for the user.
The instrument automatically applies the temperature correction and it
shows the chloride concentration on a LCD display percentage by
weight. The unit uses 4 'AA' batteries for power.
The Chlorimeter can also store test results and upload them to PC via
Once the sample is obtained, test
can be determined and read in less than five minutes. These
initial values give a valuable indicator of the current chloride
concentration values. Accurate results are typically obtained
after the sample has been in the extraction liquid for 24 hours.

to check that the system is functioning correctly. Calibration is not
required for each use. The calibration liquids are colored to avoid
confusion between them and with the extraction liquid.
