Bluelab Probe Care Kit - pH

Keep pH Probes Clean, Calibrated and Lasting Longer, Care Kit

Even small pH errors can keep plants from absorbing nutrients properly, and pH probes collect residue that slows response and causes drift. This kit removes buildup with probe cleaner and a toothbrush, then realigns the probe with a 2-point calibration. Regular care helps probes last longer and hold accuracy.

It suits growers with a single pH pen or meter and commercial teams maintaining probes on a schedule.

Frequently Asked Questions

What is the Bluelab pH probe care routine?

Clean the probe tip with pH probe cleaner and the toothbrush, hydrate it monthly and keep KCl storage solution in the cap after every use. Then calibrate at two points, pH 7.0 and pH 4.0.

Why clean before calibrating?

Residue on the probe slows its response and skews readings. Cleaning first means the calibration reflects the probe's true condition.

How often should I use the kit?

Many Bluelab pH meters show a 30-day calibration reminder, which is a sensible schedule for cleaning and calibration. Clean sooner if readings become slow or unstable.

Does the kit include KCl storage solution?

This kit lists pH 4.0, pH 7.0 and 2.77 EC sachets. KCl storage solution is available separately, and the pH and Conductivity kit includes KCl sachets.
