EC Sensor

What It Is

The Growlink EC Sensor (GL-LINK-EC-SENSOR) is a dedicated conductivity probe for the Growlink LINKS batch tankLINK controller. It connects directly to the batch tankLINK's terminal block input and feeds real-time EC data into Growlink OS, giving operators continuous visibility into nutrient solution strength without manual dip-and-read checks.

This is an accessory/replacement sensor — it is not a standalone device. The batch tankLINK controller reads the probe and handles data logging, alerting, and platform communication. If your facility already runs batch tankLINK hardware and your EC probe has drifted, fouled, or failed, this is the direct replacement.

Who It's For

Any licensed cannabis or hemp operation running Growlink's batch tankLINK for automated nutrient mixing and tank management. That includes single-facility craft operators who built out on LINKS hardware, as well as multi-site MSOs standardizing on Growlink OS across rooms or campuses.

It's also the right add-on when expanding a Growlink installation — if a second batch tank is coming online and the new tankLINK unit ships without an EC probe, or if your current probe is out of calibration range and replacement beats recalibration labor. Commercial fertigation runs continuous EC monitoring; having a verified spare on-hand is standard operating procedure for any production facility that cannot afford a feed-recipe drift event.

Key Features

The sensor is purpose-engineered for submerged, continuous-duty use in nutrient solutions — the kind of wet, chemically active environment that degrades off-spec probes quickly. It connects via the batch tankLINK's terminal block EC input, and once registered in Growlink OS, EC readings are logged alongside pH and temperature data on the controller's LCD and in the cloud dashboard.

Growlink OS stores up to 21,600 data points per sensor with graphical history, and operators can set high and low EC alarm thresholds. When the value goes out of range, on-screen and app alerts fire — so a bad mix batch or a depleting tank doesn't run undetected through a full irrigation cycle. The plug-and-play connection means swap-out time is minimal and recalibration follows Growlink's standard probe calibration workflow documented in their knowledge base.

How It Fits a Growlink Build

The Growlink LINKS platform is modular by design — each device handles one job and connects into a common network managed through Growlink OS. The batch tankLINK sits in the fertigation layer of that stack, alongside valveLINK irrigation controllers, canopyLINK sensor hubs, and climaLINK environmental sensors. The EC probe is what gives the batch tankLINK its nutrient-monitoring function; without it, the controller can track pH and temperature but cannot confirm the conductivity of the mix.

For facilities running multi-tank setups, each batch tankLINK requires its own EC probe. Continuous EC monitoring through the Growlink platform closes the loop on nutrient delivery — tank EC is tracked through mixing, the data is logged per batch, and deviations trigger alerts before the solution reaches the plants. That data trail also supports the compliance and traceability documentation many licensed operators need to maintain.
