  • Page 20 Note for the model HD2205.2: as the pH electrode non SICRAM calibration data are saved in the instrument's memory, it is important to connect the electrode in the same input used during calibration. The SICRAM pH probe calibration data are read directly in the probe's memory, so these probes do not need to be connected to the same input used for calibration.

  • Page 24: Automatic Or Manual Ph Compensation

    The electrode for pH measurement The electrode for pH measurement, generally in glass, generates an electrical signal proportional to the pH according to Nernst law. Of this signal the following aspects are considered: Zero point: The pH where the electrode generates a potential of 0 mV. In most electrodes, this value is found at about 7 pH.

  • Page 25: Ph Electrode Calibration

    In absence of the temperature probe or sensor, the lower display shows the MTC (Manual Compen- sation Temperature). If the correct value is not entered manually, the extent of the error committed in pH measurement is proportional to temperature and measured liquid pH value itself. In MTC mode, in order to manually change the compensation temperature press F5=°C/°F once: The indicated temperature value starts blinking.

    The 13 standard buffers reported in the table on page 25 are memorized in the instruments with relevant variations according to temperature: The characteristics of the three Delta Ohm standard buffers at 6.86pH, 4.01pH and 9.18pH (@25°C) are reported below.

  • Page 28: Conductivity Measurement

    Conductivity measurement The HD2206.2 and HD2256.2 work with direct conductivity/temperature probes (input ), direct 4-electrode and 2-electrode only conductivity probes (input ), or combined conductiv- ity/temperature probes with SICRAM (input ). The 4 wire Pt100, 2 wire Pt1000 sensors may be used for measuring temperature, which is used for the automatic compensation of the conductivity.
  • Page 29 The conductivity probes must be periodically calibrated. To facilitate this operation, four standard calibration solutions are automatically recognized by the instrument: • 0.001 Molar KCl solution (147μS/cm @25°C), • 0.01 Molar KCl solution (1413μS/cm @25°C), • 0.1 Molar KCl solution (12880μS/cm @25°C), •...

  • Page 31: Resistivity, Tds And Salinity Measurements

    Resistivity, TDS and salinity measurements The HD2206.2 and HD2256.2 measure electric conductivity and temperature of a solution, and cal- culates resistivity, salinity and TDS. By repeatedly pressing “F1 = cond.” (HD2206.2) and “F2 = cond.” (HD2256.2) you can select the measurement. The resistivity is defined as the reciprocal of conductivity.

    • If you get the “CAL ERROR” message during calibration, check that the input cell constant is correct. • The most frequent causes of error are due to the probe malfunctioning due to deposits, dirt or to the standard solutions deterioration (bad preservation conditions, alteration due to pollution with other solutions, …).
