AnaCONT

Manufacturer: NIVELCO(HUNGARY)

Model:  LE Series

             The AnaCONTliquid analytical transmitters are designed to measure pH, redox potential, or dissolved oxygen values of liquids and aqueous solutions. pH measurement: Continuous measurement of acidity (pH<7) and of basicity (pH>7) in liquids can be performed by the help of AnaCONT transmitters. The necessary feeding of chemicals and other technological functions can be controlled by the processed measured values. The potential difference between the submerged measuring and reference probe generates a voltage proportional to the concentration of the hydrogen ion in the measured fluid. This voltage is evaluated by the signal processing electronic module of the instrument. Based on the signals of the submerged probe and the temperature sensor the smart signal processing electronic module calculates a pH value normalized to 25°C and generates a proportional output signal. The long term stability and accuracy of the measurement requires a periodic calibrationof the sensors using the standard buffer solutions. Redox potential (ORP) measurement: Similarly to the pH measurement, the measurement of the redox potential is based on the potential difference between measuring and reference probes. Oxidation or reduction occurs on the platinum surface of the measuring probe. Redox potential is a parameter that indicates the sum of oxidants and reducers in the measured medium. The output signals of the probes are processed by the electronic unit and it converts them into a proportional output signal. In order to get the desired medium parameters the reduction of liquids or feeding of suitable oxidant is executed based on the formerly processed values.Dissolved oxygen (DO) measurement: The dissolved oxygen (DO) measurement gives the quantity of dissolved oxygen gas in the liquid, in ppm or mg/l values. The sensor with oxygen-permeable membrane immersed in the liquid provides an electronic signal proportional to the oxygen concentration. The intelligent electronics calculates and transmits the DO value normalized to 25°C on the basis of the output current of the DO sensor and the potential of the temperature sensor immersed in the medium.
