Dragino DR-ECK10.0 EC (Conductivity) Sensor

The Dragino DR-ECK10.0 is a professional EC (electrical conductivity) probe for measuring how conductive water is—one of the fastest practical indicators that salinity, mineral content, or dissolved ions have changed. That makes EC a high-value signal in systems where chemistry must stay consistent, or where salinity shifts can damage crops, equipment, or biological systems. The probe is designed to connect to Dragino WQS-LB and WQS-NB nodes and outputs data via RS485.

Industries and strong real-world use cases:

Irrigation & agriculture: Using EC to manage salinity risk in well/surface/blended water and to prevent yield loss or soil salinization.

Greenhouse / hydroponics / fertigation: EC is often the primary control metric for nutrient strength and recipe consistency.

Aquaculture, RAS, and aquariums: Monitoring salinity and mineral balance, especially where evaporation, water changes, or dosing can shift water chemistry.

Industrial water, cooling towers, and boilers: EC for concentration control, optimizing blowdown, and catching unexpected chemistry changes in closed loops.

Water reuse / treatment / intake monitoring: EC as a reliable trend signal for variable feedwater quality.

Wastewater (properly framed): EC is commonly used as an event/diagnostic indicator—for spotting salty industrial discharges, infiltration, or process-water ingress—rather than being the “main” compliance parameter.

The probe also provides salinity and TDS conversion, which is often what operators track for thresholds and reporting. With IP68 sealing, 0.6 MPa pressure resistance, and a 5 m cable, it’s built for long-term in-water deployments.
