The Bluelab Inline pH Probe is a replacement probe for the Guardian Monitor Connect In-Line.

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.

Replace only the pH probe, not the whole meter!
