Bluelab pH Controller

The Bluelab pH Controller takes the complexity out of pH management, making precision easier than ever before. That’s because the in-built peristaltic pump provides precise control, delivering doses within a 0.1 pH tolerance.

The Bluelab pH Controller is also easy to use and program; simply choose the pH control direction that’s best for your growing setup in the settings. You can either adjust for the pH-up (alkali) or pH-down (acid) direction.

This controller comes with a temperature probe, ensuring that all your pH measurements and doses will be automatically compensated for temperature. Simply set your pH target and let the Bluelab pH Controller do the rest.
