Bluelab Probe Care Kit - Conductivity

Clean, Accurate EC Probes for Dependable Feeding, Care Kit

Salt and mineral buildup on conductivity probes makes EC readings drift, so you cannot tell whether plants are under- or overfed. This kit cleans the probe and then checks it against a known 2.77 EC standard. Routine care keeps EC readings accurate and responsive.

It suits home growers maintaining a single meter and commercial teams on a cleaning schedule. Packaging may vary.

Frequently Asked Questions

Why do conductivity probes need cleaning?

Nutrient salts and minerals build up on the sensor and cause readings to drift. Cleaning restores accurate, responsive EC readings.

How do I use the kit?

Clean the probe with the conductivity probe cleaner and chamois, then test it in 2.77 EC standard solution. If the reading is not as expected, clean again; calibrate only on devices that support it, such as the Conductivity Pen and Pro Controller.

Can I use it on the OnePen?

No. Bluelab states the conductivity probe cleaner is not compatible with the Bluelab OnePen (PENONE) or OnePen Replacement Probe (PROBONE).

How often should I clean EC probes?

Clean whenever readings seem off or slow, and as part of a regular maintenance routine. Check against 2.77 EC standard afterward to confirm accuracy.
