Why the batch tankLINK

Precision nutrient control for every tank.

Without automated monitoring, growers risk inconsistent recipes, dry tanks, and wasted inputs. The batch tankLINK integrates EC, pH, temperature, and level sensors with automated refills, data logging, and real-time alerts for reliable tank management.

Four-Sensor Monitoring

Inputs for EC, pH, temperature, and tank level sensors for complete tank oversight.

Automated Refills

Level sensor input automates tank refills to prevent dry-outs and maintain consistent volumes.

Data Logging & Graphing

On-board memory stores up to 21,600 data points per sensor with graphical history on the LCD.

Configurable Alarms

Set high and low alarm thresholds for each sensor with on-screen alerts when values go out of range.

LCD Interface

Built-in LCD with three-button navigation for real-time readings, calibration, and configuration.

HUB or Wi-Fi

Connect via RJ-45 to a Growlink HUB or directly over Wi-Fi for flexible deployment.

The Growlink LINKS System
