7. BASIC INFORMATION ABOUT THE CONDUCTIVITY MEASUREMENT

The conductivity measurement is based on applying electric current with
proper voltage and frequency between two electrodes and measuring it. In
CC-411 the frequency depends on the measuring range and may vary from 1
kHz up to 12 kHz. The voltage is dependent from the kind of the measured
liquid, its concentration and temperature. The conductivity result informs
indirectly about the salt concentration in the measured liquid. The greater it
is, the higher conductivity (KCl, NaCl). This dependence doesn’t concern all
of the solutions. In some cases, after exceeding certain salinity value
conductivity starts decreasing. Temperature has also a great influence on the
results of conductivity measurement, which increases together with the
temperature rise.
The electrodes’ surface and the distance between them have decisive
influence on the K constant value of the cell. This value has a great influence
on the accuracy of the measurement. Depending on the measured
conductivity value cells with K constant = 0.05 cm

-.1

up to 1.500 cm

-.1

are
used. During measurement the meter multiplies the measured value by the K
constant introduced to the meter’s memory and displays the result in units of
conductivity (µS/cm or mS/cm). Shortened symbol of the unit is displayed next
to the result (µS or mS). Conductivity is affected by the temperature and
salts concentration. In order to enable comparing of the results, measured
value is counted by the meter to the value which corresponds to measurement
in 25 0C. Measurement in this temperature is the most accurate. In other
temperatures there is temperature compensation used, which means that the

meter takes currently measured temperature and α coefficient into
consideration. This coefficient describes how much the result will change

when the temperature change is 1 0C. The α coefficient in this meter is
constant and equal 2% / 0C. This is the closest value to that of most of the
salts in 25°C. For example if measurements are made in liquid of temperature
coming to 30 0C, the result change will total up to 5 x 2% = 10%.
The conversion is made automatically and this change is counted into the
result. The conductivity measurement should always be treated as burdened
with a certain error, which depends on the conductivity cell (its linearity) and
temperature. When measurements are not made in the reference

temperature, the error is dependent mainly on the α coefficient, which is
affected by the temperature and concentration changes.

8. CHOICE AND MAINTENANCE OF THE CONDUCTIVITY CELL

8.1. Choice of the conductivity cell

Conductivity in CC-411 meter can be measured in range
0 – 100 mS/cm. The meter co-operates with conductivity cells with K constant
= 0.050 ÷ 1.500 cm-1 and equipped with BNC-50 connector. Depending on
the required measuring range it is necessary to choose appropriate cell with K
constant which enables obtaining accurate results. Beyond the range the cell
looses its linearity and the results have greater error. Accurate measurements
in the whole range are possible with use of 2 different conductivity cells.
In range 1 – 100 mS/cm the standard conductivity cell with K constant =1 cm

-

1

should be used.

For measurements of ultra pure water with conductivity below 1 µS/cm a cell
with K constant = 0.1 cm-1 should be used.
Depending on the expected measuring range, choose the appropriate cell
using the chart below (Pic.6).

Pic. 6. Dependence between the measuring range and of applied conductivity
cells.

- 17 -

8.2. The conductivity cell maintenance

In order to receive stable results, it is advisable to store the cell in water for a
few hours before the measurement, this is especially required in case of
distilled water measurements.
The conductivity cell maintenance consists mainly in accurate washing the
inside of the measuring cell with distilled water. The platinum electrodes must
not be cleaned mechanically, because this results in rubbing off the platinum
layer, what can cause decreasing of accuracy, lowering of stability and
changing of the K constant.
Measurements of liquids with oils and heavy-sediment content may cause
platinum contamination, make the measurement impossible and irreparably
damage the electrodes. In case of fat content in the measured liquids it is
possible to clean the electrodes by immersing the cell in acetone, chloroform,
fourhydrofuran or detergent.
Certain norms recommend universal liquid for cleaning cells. This is a
mixture of equal parts of isopropyl alcohol, ethyl ether and hydrocholic acid,
diluted with water in 1:1 ratio.
Breaking of the measuring cell hinders any further measurements due to
significant change of the K constant, unstable results and increase of the
dependence of the result on the position of the cell in the measuring vessel.
The cell should be immersed in such a way for the solution to fill it up and not
to include any air bubbles (single bubbles or silver coating). It is essential for
obtaining accurate results of measurements. The best way is to immerse the
cell, make a few vertical moves and thus to remove air bubbles through holes
in the upper part of the cell. If the air bubbles appear each time after the cell
has been immersed and they are difficult to remove, it is advisable to
immerse the cell in a water – washing up liquid mixture, what will lower the
surface tension and disable air bubbles to stick to the surface of the cell walls
or electrodes. After such action the cell should be washed accurately in
distilled water.

9. CALIBRATION OF THE CONDUCTIVITY CELL

Characteristic feature of every conductivity cell is its K constant. Before
displaying the result on the display the value is multiplied by the K constant
value. The value of the K constant depends on the size of the electrodes’
surface and the distance between them. If the user keeps the cell clean, the
K constant does not change. In case of contamination of the surface of the
electrodes, the K constant will change.
Calibration may be performed without the sample solution, by entering the
value of the K constant of the cell given by the manufacturer to the meter’s
memory (we recommend this kind of calibration) or with use of standard
solution with known conductivity, to determine the K constant.

The K constant is precisely determined by the cell manufacturer and
using this value will be the most reliable.
In case of calibration performed by the user, fresh, accurately prepared
standard solution is required. Additionally it has to be accurately
thermostatic to 250C. If the conditions won‘t be kept the calibration may
be burdened with error.

9.1. Calibration without the standard solution

The meter has a possibility of calibration without the use of standard solution.
For such calibration, it is necessary to know the K constant of the conductivity
cell. This value may be given by the cell manufacturer or may be determined
using the CC-411 meter after calibrating it in the standard solution.
In order to calibrate:

- in the conductivity measuring mode press the button till the moment

of displaying the symbol in the bottom row and the k symbols and
the value of the K constant introduced earlier in the upper row.

- with the , buttons enter the value of the K constant;

- return to the measuring mode by pressing and holding the

button.

9.2. Calibration with use of standard solution

The meter enables one-point calibration in a freely chosen standard solution,
to determine the K constant of the cell. In order to decrease the error, it is
recommended to use solutions with value close to the estimated value of
measurement. It is required to use standard solutions of a high quality.

11. SALINITY MEASUREMENT

Salts and minerals dissolved in natural water influence the conductivity,
which in principle is proportional to the quantity of dissolved substances. This
dependence enables, after certain calculations, to determine the salinity of
the measured solution in concentration units (g/l or %). Received values are
always approximate and the total accuracy depends on the way of making
calculations, concentration of the measured solution and its temperature. In
most salinity meters a simplification is used, that dependence between
conductivity and salinity in the solution is linear in the whole measuring
range. Usually a 0.5 coefficient is used, the conductivity result in mS/cm is
multiplied by this coefficient and the result of salinity is received in g/l, e.g., if
the conductivity value is 2 mS/cm the salinity is 1g/l. In practice the
dependence between conductivity and salinity isn’t linear and the conversion
coefficient is changing together with the concentration and temperature.
Table 1 shows the dependence between conductivity and actual salinity of
NaCl solution in temperature 25 0C and values of salinity counted for
constant coefficient 0.5. This comparison shows that using a constant
coefficient for greater concentrations introduces significant error.

14. POWER SOURCE AND CHANGING THE BATTERY

The meter is powered by 9V battery or 12V stabilised power adapter. The
adapter should be joined with the P connector (Pic.2). Connecting the power

adapter disconnects the battery and is signalised by the symbol.
The symbol informs about the battery condition. Flashing of the
symbol informs that the battery should be changed. In order to do so, it is
necessary to undo two screws in the lower wall of the meter, pull out the
whole wall and replace the battery.
The next thing is to put the new battery into the meter and mount the wall.
The wall has a sealing ring at the edge. While closing the meter, it is very
important to pay attention if the ring is put inside the housing in the whole
perimeter. Next, do the screws till the moment of resistance (not too hard).
Leaving the wall improperly screwed may cause the meter’s inundation,
which is not repaired under the warranty conditions.
