Conductivity Salinity Sensor for the most fouling application

The CTZN sensor uses an inductive method with ring-type coils, providing low maintenance and consumable-free technology. Its measurement technology ensures stable and accurate conductivity and salinity readings in demanding environments.

Why measure conductivity in water?

Measuring conductivity in water is crucial for assessing water quality. It provides insights into the water’s ability to conduct electrical currents, a key indicator of dissolved ions and contaminants, salinity levels, and overall water health. Understanding conductivity aids in identifying potential pollution sources, ensuring early intervention for effective water management. Whether in urban wastewater, industrial effluent, or marine environments, regular conductivity monitoring with Aqualabo’s advanced sensors empowers industries and environmental authorities to make informed decisions, promoting sustainable water usage and safeguarding aquatic ecosystems.

Main applications of conductivity measurement in water

Conductivity measurement stands as a cornerstone in diverse water applications. Aqualabo’s advanced sensors find indispensable use in urban wastewater treatment, ensuring compliance with stringent quality standards. In industrial effluent control, conductivity monitoring becomes pivotal for maintaining discharge parameters. Surface water monitoring benefits from accurate assessments, identifying variations and potential contaminants. In sea water analysis, our probes provide valuable insights into marine ecosystems; moreover, conductivity measurement proves crucial in optimizing conditions for aquaculture.

Measurement principles used by Aqualabo’s conductivity CTZN/C4E probes

Aqualabo’s conductivity sensors employ cutting-edge measurement principles to ensure accurate and reliable data. The CTZN sensor with a measuring range from 0 to 100 mS/cm utilizes an inductive method with ring-type coils, creating a robust system that requires minimal maintenance and avoids consumables. This technology facilitates consistent conductivity readings in demanding water conditions. On the other hand, the C4E sensor with a measuring range of 0 to 200mS/cm employs a sophisticated 4-electrode system. By using alternating current and constant voltage, this system regulates voltage, compensating for fouling, and guarantees precise measurements even in challenging environments. Aqualabo’s commitment to innovative measurement principles ensures dependable conductivity assessments for applications ranging from urban wastewater to sea water monitoring.
