Bluelab pH Probe Replacement

Technology That Defies Time (and Errors)

In high-stakes cultivation, a faulty pH probe is a luxury no one can afford. The double-junction design isn’t just a buzzword—it slashes electrolyte contamination, a common flaw in budget probes that causes erratic readings and short lifespans. Unlike single-junction models, the reference electrolyte here acts as a chemical barrier, shielding the core from metal ions or organic debris. The result? Stability that endures months of heavy use in acidic or alkaline solutions.

Built for Hostile Environments

This probe’s 100% waterproof rating (not just resistant) is no accident. Hermetic sealing and polycarbonate housing withstand prolonged immersion in reservoirs, corrosive nutrient splashes, or aggressive cleanings. The 2-meter cable, shielded against electromagnetic interference, lets you measure hard-to-reach corners of grow tents or complex hydroponic setups without moving your meter.

Why is pH Your Ally (or Your Enemy)?

Cannabis absorbs each nutrient within a strict pH range—iron, for example, locks out above pH 6.5 in soil. This probe detects microscopic deviations (0.01 pH), enabling real-time adjustments. It thrives in low-EC environments (0.2) where other probes fail, and its 15-second response time eliminates delays during large-scale feedings.

Recommendations:

🔹 Calibrate the probe before using it for the firts time. When the probe is uncalibrated, the Guardian/Combo will alert you.

🔹 After each use, rinse with distilled water and store with the cap filled with the Storage Solution.

🔹 Perform a deep cleaning every 2-3 weeks. Use the cleaner from the pH Probe Maintenance Kit.
