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.

Bluelab pH Probe Features

  • Easy to clean
  • Gel filled (non-refillable)
  • Double junction
  • Waterproof cable joint
  • Probe holder included – keeps probe secure
  • Quality BNC connection
  • 2 metre / 6.56 foot standard cable

Replace only the pH probe, not the whole meter!
