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

Ensure Optimal Nutrient Uptake with Continuous pH Monitoring from the Growlink TankLINK pH Sensor

The Growlink™ LINKS Batch TankLINK pH Sensor delivers precise, real-time pH measurements of nutrient solutions in batch tanks, providing the continuous data needed to maintain the stable pH range that maximizes nutrient availability and plant health. Designed for plug-and-play integration with Growlink TankLINK systems, it feeds pH readings directly into the Growlink automation ecosystem, enabling automated alerts and pH correction responses without manual sampling.

Featuring a 10-foot cable for flexible installation positioning, the pH Sensor connects seamlessly into the broader Growlink LINKS infrastructure. A 30-foot cable option is available separately for larger tank configurations requiring extended reach. When combined with the TankLINK EC and temperature sensors, it provides a complete view of nutrient solution chemistry for fully automated batch tank management.

Key Features & Benefits

• Real-time pH monitoring — continuously measures nutrient solution pH to ensure it remains within the optimal range for nutrient solubility and plant uptake.
• 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 or more complex installations.
• Automation-ready data — pH readings integrate with Growlink OS to trigger alerts or automated pH correction responses when values drift outside target ranges.
• Supports consistent nutrient delivery — stable pH management ensures nutrients remain soluble and available to plants throughout every feeding cycle.
• Durable sensor design — built for reliable long-term performance in continuous nutrient solution contact.

Who Should Use the Growlink TankLINK pH Sensor

This sensor is essential for indoor cultivators and commercial growers running batch nutrient systems where pH stability directly impacts crop health and yield consistency. It is particularly valuable in operations using the Growlink Batch TankLINK for centralized nutrient management, where real-time pH data drives automated correction and refill actions through the Growlink platform.

pH Management and Nutrient Availability in Indoor Cultivation

pH is one of the most critical variables in nutrient solution management — even small deviations from the optimal range can lock out essential nutrients, causing deficiency symptoms and reducing plant performance regardless of how much nutrient is present in the solution. The TankLINK pH Sensor removes the need for manual pH testing by providing continuous, real-time data that integrates directly with Growlink's automation layer, allowing cultivators to maintain precise pH control across every batch without interrupting their workflow.

Frequently Asked Questions

Why is pH monitoring critical for nutrient solution management?

pH determines the solubility and availability of individual nutrients in the solution. Most nutrients are optimally available within a narrow pH range. Outside this range, specific nutrients precipitate or become unavailable for plant uptake, causing deficiencies even when nutrient concentrations are correct.

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

Yes. The TankLINK pH Sensor is designed 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 pH Sensor includes a 10-foot cable, a 30-foot cable option is available separately for installations where the sensor needs greater reach within large-volume or remotely positioned batch tanks.

Can the pH Sensor trigger automated pH correction?

Yes. When integrated with the Growlink Batch TankLINK and automation platform, pH readings can trigger connected dosing pumps to automatically adjust pH up or down, or alert the operator when values fall outside programmed target ranges.

How often does the pH Sensor need to be calibrated?

Regular calibration is essential for pH sensor accuracy, as pH electrodes drift over time. Consult Growlink's documentation for the recommended calibration schedule and procedure for TankLINK pH sensors in your environment.
