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

Keep Nutrient Solution pH in Range Without Manual Sampling

Even a small pH drift can lock out nutrients a plant would otherwise have full access to, and manual pH testing only ever captures a single moment in time. The Growlink Batch TankLINK pH Sensor removes the guesswork by continuously reading nutrient solution pH in a batch tank and feeding that data directly into the Growlink automation ecosystem for correction alerts and logging.

It installs plug-and-play with a 10ft cable long enough for most reservoir layouts, with a 30ft cable version available separately for larger or more distant tanks, and pairs with the Batch TankLINK EC, temperature, and level sensors for a complete view of solution chemistry.

Key Features & Benefits

• Continuous pH Monitoring: Tracks nutrient solution pH in real time rather than relying on periodic manual testing.
• Plug-and-Play TankLINK Integration: Connects directly into the Batch TankLINK system without added configuration.
• 10ft Cable, 30ft Option Available: Standard cable reaches most reservoir setups, with a longer option sold separately.
• Automation-Ready Data: pH readings can trigger Growlink OS alerts or connected dosing responses when values drift.
• Pairs With EC, Temperature & Level Sensors: Combines with other Batch TankLINK sensors for a full solution-chemistry picture.

Who Should Use This

Growers running batch nutrient reservoirs who want continuous pH visibility and automated drift alerts, rather than periodic handheld testing, are the direct fit for this sensor, particularly operations already using the Batch TankLINK Tank Monitor.

About Growlink

Founded in 2015, Growlink extends its TankLINK nutrient monitoring hardware with dedicated pH sensing, joining EC, temperature, and level sensors under one Growlink OS platform.

Frequently Asked Questions

Why does even a small pH shift matter for nutrient uptake?

Most nutrients are only fully soluble and available within a fairly narrow pH band. Outside that band, specific nutrients can precipitate out of solution or become chemically locked, causing deficiency symptoms even when the correct nutrients were dosed.

Does this sensor require the Batch TankLINK Tank Monitor?

Yes, the pH Sensor is built to connect through the Growlink Batch TankLINK system. A TankLINK unit is required to bring its readings into Growlink OS.

How is this sensor calibrated?

Like most pH electrodes, this sensor drifts gradually over time and benefits from periodic calibration against known reference solutions. Check Growlink's documentation for the recommended calibration interval for your specific installation.

Can pH readings trigger an automated correction?

Yes, when paired with connected dosing equipment, pH data can trigger automatic up or down correction, or simply alert an operator when values drift outside a configured range. Which behavior fires depends entirely on how the automation rule is configured in Growlink OS.
