Reliable EC measurement in water

Seymour's conductivity sensor measures the EC of water continuously and accurately, with automatic temperature compensation for a stable reading. It installs submerged (3/4 NPT thread) and is built to withstand field conditions and prolonged water exposure (IP68 rating).

The sensor integrates with Seymour's stations — for example in the Runoff Station to measure the EC of irrigation and runoff — and transmits the data to the controller and the cloud.

Why the Seymour conductivity sensor

Continuous measurement in water

EC of irrigation water, runoff and water treatment — a key parameter for fertigation and water-quality management.

Automatic temperature compensation

A built-in Pt1000 sensor ensures a stable, accurate EC reading at any water temperature.

Durable & integrated

An IP68 rating and submerged installation, with an RS485 / 4–20mA interface that integrates with Seymour's stations.
