Bluelab OnePen Replacement Probe

Product detailed description
Replacement probe for Bluelab OnePen
OnePen measures both pH and conductivity (EC) with a single probe – and this probe wears out over time. Instead of buying a new pen, simply replace this spare probe and the OnePen will regain its pH measurement accuracy of ±0.05.
Compatibility
Designed exclusively for the Bluelab OnePen. The probe combines a pH electrode with a double junction and titanium conductivity electrodes, so after replacement, both pH and EC measurements remain integrated. The average probe lifespan is approximately 18 months.
Storage and Care
Store in KCl storage solution and do not let the probe dry out. Regular pH calibration is performed with two-point solutions pH 4 and pH 7.
