pH replacement probe

R1 670 - R1 820


The Bluelab pH Probe is a replacement pH probe (electrode) suitable for use with Bluelab products that test the pH value of a solution.
Unfortunately, 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 wet and cleaning once a month), you will extend its life.
The Bluelab pH Probe has a double junction reference which provides a longer life than many other pH probes and is a gel-filled non-refillable probe, so apart from cleaning is maintenance-free.

For use with Combo MeterCombo Meter PlusMultimedia pH Meter or any Bluelab product with a BNC style connection. 

Replace only the water pH probe, not the whole meter!
