Bluelab pH ProbePlus

Over time, pH probes naturally wear. Instead of replacing your entire device, the Bluelab pH ProbePlus lets you simply swap in a new probe and keep your Bluelab pH PenPlus performing like it should. It’s a straightforward way to maintain accuracy, protect your investment, and avoid unnecessary downtime.

Designed for easy replacement, the probe can be changed quickly with no tools required. Keeping a spare on hand means you’re always ready to restore performance the moment readings start to drift, so you can continue growing with confidence.

Accurate pH measurement starts at the probe. The Bluelab pH ProbePlus features a double-junction design to support stable, consistent readings across a range of growing environments, helping you make better decisions around nutrient availability and plant health.

With a KCl-filled storage cap to help maintain probe condition between uses, it’s built to support ongoing performance when properly cared for. Pair it with the Bluelab pH Care Kit to clean, calibrate, hydrate and extend the life of your probe, so you can rely on every reading.
