1. INTRODUCTION
1.1. APPLICATION
The AnaCONT compact transmitters, liquid analytical instruments are suitable for high precision measurement and transmission of acidity or alkalinity - pH
(Hydrogen ion concentration) value -, reducing and oxidizing capability - ORP (Oxidation Reduction Potential) value -, or Dissolved Oxygen content of process
water, wastewater, surface water, ground water and drinking water. These measurements can be widely used in industrial practice and could be of great
relevance. In the field of environmental protection or sewage treatment, instruments like that are suitable for measuring the concentration of hazardous
substances (chromium, cyanide). In chemical- and pharmaceutical industry, high precision measurement has utmost importance in the aspect of the technology
(e.g. solvent feed), in many cases it is quality specification standard.
1.2. OPERATION PRINCIPLE
The intelligent signal processing of the electronics calculates the output signal from the voltage output values of the
electrode and the temperature probe, and compensates it to 25°C. This value composes the basis of all output
signals of the instrument.
1.2.1. Characteristics of an ideal pH electrode

ion concentration of the liquid.
0mV output at neutral pH value (pH=7.00)
Positive voltage output in acidic liquids (pH<7)
Negative voltage output in alkaline liquids (pH>7)
Total measuring range is 0-14pH
-59.16mV/pH (Nernst potential) slope at 25 °C
The temperature dependency of the Nernst potential is -0.001984 mV / °C.

Because the pH electrodes in deed are not ideal (their properties depend on the design of the electrode, manufacturing tolerances and most of all the age of the
electrode) the parameters differ from the given values above. To achieve reliable pH measurement and accuracy these electrodes must be calibrated from time
to time. The time interval between two calibrations depends on the application conditions where the pH probes are used. Calibration of pH electrodes means
offsetting the displayed value (7.00pH) when gauging neutral buffer solution, and adjusting the slope (pH/mV) by measuring buffer solutions with other pH value
(usually with 4.00pH and 10.00pH value) by adjusting the displayed value to exact 4.00 and 10.00pH, respectively.

1.2.2. Characteristics of an ideal ORP electrode
Negative voltage output in liquids with reduction potential,
Positive voltage output in liquids with oxidation potential,
Output voltage is equal to the redox potential (according to the Nernst equation)
pH independent measurement with certain types
To achieve reliable measurement and accuracy, these electrodes have to be thoroughly checked before
installation and during usage from time to time. The time interval between two calibrations depends on the
application and conditions where the ORP probes are used.
1.2.3. Characteristics of an ideal DO sensor
The dissolved oxygen level indicates the amount (in mg/l or ppm) of physically dissolved gas-form oxygen in
liquid phase.
Oxygen-permeable membrane amperometric DC sensor wetted in the measurement medium gives output
c
urrent proportional to the dissolved oxygen concentration of the medium.

Dissolved oxygen (DO), ppm sat´n0
Slope = /ppm oxygen Output current of the
DO sensor
The ideal DO sensor has:
Izero=0,
Temperature independent output current
Real DO sensor gives off a minimal Izero≠0ppm current in case of 0 ppm dissolved oxygen concentration and its oxygen-permeable capability is temperature-
dependent. Oxygen-permeable capability of the membrane is increasing according to the increase of the temperature, at 25 °C it can be 4%/°C. Temperature
proportional correction is necessary for reliable measurement.
The DO sensors in deed are not ideal (their properties depend on the design of the electrode, manufacturing tolerances and most of all the age of the electrode),
so the parameters differ from the given values above. To give reliable DO measurement and accuracy these electrodes must be calibrated from time to time. In
case of DO sensors the calibration means that 0 ppm output value have to be set by offsetting in an oxygen-free solution. For DO measurement of other
mediums (for example dry air 20.95%@25°C or oxygen-saturated water) adjustment of slope (nA/ppm) has to done accurately according to the properties of
these mediums.
