Bluelab pH Pen Plus Replacement Probe

Product detailed description

Replacement Probe for Bluelab pH Pen Plus

The pH probe is a consumable part – it wears out over time and slows measurement. However, with the Bluelab pH Pen Plus, you do not need to replace the entire device: simply screw on this replacement probe and the pen will regain its accuracy of ±0.1 pH within the range of 0 to 14 pH.

Compatibility

Designed exclusively for the Bluelab pH Pen Plus. The probe features a screw-cap design for quick replacement without tools. It is not compatible with other Bluelab pens (pH Pen, Soil pH Pen) which have fixed probes.

Storage and Care

The probe comes with a silicone cap filled with KCl storage solution and an internal sponge to keep it hydrated. Never let the glass probe dry out – store it in KCl solution and measure in solutions with EC from 0.2 upwards. The probe has a 6-month warranty.

Frequently Asked Questions

Does this probe fit the regular pH Pen?

No. Only the Bluelab pH Pen Plus has a replaceable probe. The basic pH Pen and Soil pH Pen have fixed probes, so the entire pen must be replaced, not just the probe.
