The Bluelab pH PenPlus. pH confidence you can swap back in
The difference is simple. When natural probe wear occurs, the probe can be replaced, not the whole pen. Simply swap out the probe to quickly restore performance.
Built to IP68 standards, dustproof, waterproof, and designed for demanding environments, the pH PenPlus encourages long-term use while protecting your workflow and investment.
The Bluelab pH PenPlus is about readiness. Keeping a replacement Bluelab pH ProbePlus on hand means less downtime, less disruption and continued confidence in every reading.
Get the fundamentals of runoff right, every time
Healthy plant growth starts with the right pH. In hydroponic and irrigated systems, plants can only access nutrients when the root zone stays within the right pH range.
Measuring runoff helps you understand what is happening around the roots. It shows whether your nutrient solution is staying available to the plant, or whether the root zone is drifting too acidic or too alkaline for efficient nutrient uptake.
By checking pH and Temperature in your runoff, you can spot changes early, make informed adjustments, and keep your crop in the optimal range for healthy plant growth.
