Thanks to smart digital technology, Aqualabo sensors, including CTZN and C4E, store calibration data internally, offering a plug and play experience without the need for frequent recalibration. Regular maintenance may include cleaning the electrodes, checking for damage and calibrating the sensors. The CTZN (inductive) requires minimal maintenance due to its resistance to fouling, making it a practical choice for installations where access for maintenance may be limited. While generally low maintenance, the C4E (4-electrode system) sensor may require more attention in environments prone to fouling.
