AquaSense-EC Overview

AquaSense-EC is a two-electrode graphite conductivity / TDS sensor designed for online water-quality monitoring. The graphite cell offers strong corrosion resistance, and an isolated power-supply design improves measurement stability in noisy electrical environments. A built-in high-accuracy NTC temperature element handles automatic temperature compensation across the operating range.

The sensor outputs RS485 with the Modbus RTU protocol, making it easy to wire into existing telemetry and SCADA networks. The two-electrode cell is well suited to low- to mid-range conductivity in fresh water, drinking water, and many process applications.
