Bluelab Inline pH Probe (Replacement Probe Guardian Monitor In-Line) 600 Watt Double Ended HPS & MH Grow Lights vines and rosesThe Bluelab Inline pH Probe is a replacement probe for the Guardian Monitor 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!
