pH and ORP Transmitters Continuous measurement of acidity (pH7) of liquids can be performed with the compact transmitter, feeding of chemicals and other process functions can be controlled by the processed measured values.
The potential difference between the submerged measuring probe and reference probe is proportional to the concentration of the hydrogen ions in the measured fluid. This voltage is processed by the signal processing electronic module of the instrument. The smart signal processing electronic module calculates the pH value normalized to 25°C from the output values of the submerged probe and the temperature sensor and generates a proportional output signal.
