Inductive conductivity sensor solution

Complete monitoring solution including sensor, logger, connectivity and cloud.

The Conductivity solution is built around the LDL400 inductive conductivity sensor for reliable water quality measurement in wastewater and process water applications. The inductive measurement principle enables accurate readings without direct electrode contact, making it highly resistant to fouling and corrosion from aggressive or saline media.

All data is logged and transmitted automatically to the cloud, allowing operators to monitor water quality in real time and receive alarms if abnormal conditions occur.
