AnaCONT LEP / LER- pH and ORP Transmitter

AnaCONT liquid analytical transmitters (pH and ORP Transmitter) are designed to measure pH, redox potential or dissolved oxygen values of liquids and aqueous solutions.

pH measurement: With the help of AnaCONT transmitters, continuous acidity (pH7) measurement can be made in liquids. The necessary supply of chemicals and other technological functions can be controlled with the processed measured values. The potential difference between the immersed measurement and the reference probe produces a voltage proportional to the concentration of the hydrogen ion in the liquid being measured. This voltage is evaluated by the signal processing electronic module of the device. The intelligent signal processing electronics module calculates a pH normalized to 25°C based on the signals from the submerged probe and temperature sensor and generates a proportional output signal. The long-term stability and accuracy of the measurement requires periodic calibration of the sensors using standard buffer solutions.

Redox potential (ORP) measurement: Similar to pH measurement, the measurement of redox potential is based on the potential difference between the measurement and reference probes. Oxidation or reduction occurs on the platinum surface of the measuring probe. The redox potential is a parameter that represents the sum of oxidizers and reductants in the measured medium. The output signals of the probes are processed by the electronic unit and convert them into a proportional output signal. To achieve the desired ambient parameters, the reduction of liquids or the supply of the appropriate oxidizer is carried out according to the previously processed values.

(DO) measurement: Dissolved oxygen (DO) measurement gives the dissolved oxygen gas amount in the liquid in ppm or mg/l values. The immersed oxygen-permeable membrane sensor provides an electronic signal proportional to the oxygen concentration. The intelligent electronics calculate and transmit the DO value normalized to 25°C based on the output current of the DO sensor and the potential of the immersed temperature sensor.
