Bluelab pH Controller® Connect

Clever monitoring, dosing and data logging of solution pH levels. Made easy.

Better knowledge can make a world of difference when it comes to managing the pH of nutrient solutions.

The intelligent pH Controller Connect constantly monitors and fine-tunes pH levels automatically. But more than that, via a wireless connection it can log data to a computer too, giving continuous information to the grower. The data can be used to make system changes faster for the ultimate crop, and the settings can be changed from the PC.
