Growlink LINKS Batch TankLINK EC Sensor — 10ft Cable Compatible with TankLINK Systems

Maintain Optimal Nutrient Concentrations with the Growlink TankLINK EC Sensor

The Growlink™ LINKS Batch TankLINK EC Sensor delivers precise, real-time electrical conductivity (EC) measurements to ensure nutrient concentrations in batch tanks remain within the optimal range for healthy, productive plant growth. Designed for plug-and-play integration with Growlink TankLINK systems, it provides the continuous data needed to support consistent feeding schedules and automated nutrient management without manual sampling.

Featuring a 10-foot cable for flexible installation positioning, the EC Sensor connects directly to the Growlink automation ecosystem, allowing EC readings to trigger automated responses — from nutrient dosing to system alerts — through Growlink OS. A 30-foot cable option is available separately for larger tank setups requiring greater reach.

Key Features & Benefits

• Real-time EC monitoring — continuously measures electrical conductivity to track nutrient solution strength and ensure consistent delivery to crops.
• Plug-and-play TankLINK compatibility — connects directly to Growlink TankLINK systems for immediate integration without complex configuration.
• 10-foot cable — provides flexible positioning within batch tank setups, with a 30-foot option available for larger installations.
• Automation-ready data — EC readings integrate with Growlink OS to trigger automated dosing, alerts, or refill actions based on programmed target ranges.
• Supports consistent feeding schedules — eliminates manual EC sampling by providing continuous data for reliable, repeatable nutrient management.
• Durable design — built for long-term submersion and reliable performance in nutrient solution environments.

Who Should Use the Growlink TankLINK EC Sensor

This sensor is essential for indoor cultivators and commercial growers running batch nutrient systems who need accurate, automated EC monitoring to maintain consistent solution strength. It is particularly valuable in operations using the Growlink Batch TankLINK for centralized nutrient management, where EC data directly drives dosing and refill automation through the Growlink platform.

Automated Nutrient Management Through EC Monitoring

Electrical conductivity is the primary indicator of nutrient solution strength — and keeping it within the optimal range for each crop stage is one of the most impactful variables in indoor cultivation outcomes. By continuously monitoring EC and feeding that data into Growlink's automation layer, the TankLINK EC Sensor removes the guesswork from nutrient management, enabling cultivators to maintain precise solution concentrations across every batch without manual intervention.

Frequently Asked Questions

What does EC measure and why does it matter for plant growth?

EC (electrical conductivity) measures the concentration of dissolved salts in a nutrient solution, which directly indicates nutrient strength. Maintaining EC within the target range for each growth stage ensures plants receive the right nutrient load — too low causes deficiencies; too high causes salt stress and toxicity.

Does the EC Sensor require the Growlink Batch TankLINK to function?

Yes. The TankLINK EC Sensor is designed specifically for use with the Growlink Batch TankLINK system. A TankLINK unit is required to connect the sensor to the Growlink platform for monitoring and automation.

Is a longer cable available for larger tank setups?

Yes. While the standard EC Sensor includes a 10-foot cable, a 30-foot cable option is available separately for installations where the sensor needs to reach further into large-volume batch tanks or remote tank positions.

Can the EC Sensor trigger automated nutrient dosing?

Yes. When integrated with the Growlink Batch TankLINK and automation platform, EC readings can be used to trigger connected dosing pumps or alert the operator when concentrations deviate from target ranges.

How often does the EC Sensor need to be calibrated?

Regular calibration is recommended to maintain measurement accuracy. Consult Growlink's documentation for the recommended calibration schedule and procedure for TankLINK sensors in your specific cultivation environment.
