Bluelab Probe Care Kit – pH and Conductivity

Complete Care for pH and EC Probes in One Kit, Clean + Calibrate

pH and EC probes both drift as nutrient salts, oils and organic matter build up, and inaccurate readings lead to nutrient imbalance. This complete kit cleans both probe types, calibrates pH, checks EC accuracy and refills storage caps. It restores accuracy and response time and helps extend probe life.

It suits growers who use both pH and EC meters, or a combo meter, and want one kit for the full maintenance routine.

Key Features & Benefits

• Two cleaners — pH probe cleaner and conductivity probe cleaner, 30 ml each.
• Cleaning tools — toothbrush, chamois and three plastic cups.
• Full sachet set — 2x each of pH 4.0, pH 7.0, 2.77 EC standard and KCl storage.
• Care instructions — step-by-step probe care guide.

Frequently Asked Questions

What does the complete kit include?

Probe care instructions, three plastic cups, pH and conductivity probe cleaners, a toothbrush and a chamois. Solutions include 2x each of pH 4.0, pH 7.0, 2.77 EC standard and KCl storage sachets.

How do I care for the conductivity probe?

Clean the probe tip with conductivity cleaner and the chamois, then test in 2.77 EC standard. Clean again if the reading is off; calibrate only on devices that support it, such as the Conductivity Pen and Pro Controller.

How do I care for the pH probe?

Clean with pH probe cleaner and the toothbrush, keep KCl in the storage cap and calibrate at pH 7.0 then pH 4.0.

Is it compatible with the OnePen?

The conductivity probe cleaner is not compatible with the Bluelab OnePen (PENONE) or OnePen Replacement Probe (PROBONE).
