Bluelab Replacement pH Probe

A replacement probe for Bluelab Combo and pH Meters, and Guardian Monitors

The Bluelab pH Probe is a replacement pH probe (electrode) suitable for use with Bluelab products that test the pH value of a solution.

pH probes do not last forever as they age through normal use and will eventually fail. 

With good care and use (keeping the probe tip moist and cleaning once a month) its life will be extended.

The Bluelab pH Probe has a double junction reference providing longer life and is a gel-filled non-refillable probe, so it is maintenance-free.

Replace only the pH probe, not the whole meter!

pH Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller.

If the probe is contaminated or dirty, it affects the accuracy of the reading displayed. pH probes are scientific instruments and should be cleaned and calibrated regularly to extend their life.
