Dragino DR-ECK1.0 EC (Conductivity) Probe

The Dragino DR-ECK1.0 is a rugged EC (electrical conductivity) probe designed for lower-to-mid conductivity ranges—ideal when you want to track cleaner water or controlled processes where small changes matter. It connects to Dragino WQS-LB and WQS-NB nodes and outputs readings via RS485, making it a good fit for permanent, field-deployed monitoring points.

Popular industries and strong real-world use cases:

Drinking water & treatment: Using EC as an early indicator of quality shifts, blending changes, or unexpected ingress in treatment and distribution.

Water treatment / RO / near-pure water processes: Trend monitoring to confirm treatment steps are performing and to spot changes in ionic content in feed or permeate lines.

Freshwater aquaculture / RAS & aquariums: Monitoring mineral balance and catching drift caused by evaporation, water changes, or dosing.

Greenhouse / hydroponics (lower EC zones): Fine control in growth phases where EC targets are lower and high resolution helps keep recipes consistent.

Industrial water (feed/rinse water): Detecting chemistry changes, mixing, or residual conductivity after rinsing and process steps.

The DR-ECK1.0 measures K=0 to 2000 µS/cm with 1 µS/cm resolution and ±1% FS accuracy. It also provides TDS and salinity conversion, which many operators prefer for reporting and thresholds. A built-in temperature sensor measures -20 to 60 °C. With IP68 sealing, 0.6 MPa pressure resistance, and a 5 m cable, it’s built for long-term direct in-water installation.
