    - 15 - 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.

  • Page 22: Choice And Maintenance Of The Conductivity Cell

    - 16 - 8. CHOICE AND MAINTENANCE OF THE CONDUCTIVITY CELL 8.1. Choice of the conductivity cell Conductivity CC-411 meter measured 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.

  • Page 23: The Conductivity Cell Maintenance

    - 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.

  • Page 24: Calibration Of The Conductivity Cell

    - 18 - 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.

  • Page 25: Calibration With Use Of Standard Solution

    - 19 - 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.
  • Page 26 - 20 - 9.2.2. Calibration without the temperature compensation Accurate calibration should processed without temperature compensation. The sample solution should be brought to 25° C.

  • Page 31: Conductivity Measurement In Honey

    - 25 - 10.4. Conductivity measurement in honey The unit of conductivity of honey given by literary sources is 10 S/cm, which means that one unit of conductivity of honey is equal 100 µS/cm. If the meter indicates 250 µS/cm, it will inform about 2,5 units of honey conuctivity. If the readout is equal 1,5 mS/cm, it will be equal 15 units of the conductivity of honey.

  • Page 32: Salinity Measurement

    - 26 - 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.
