A replacement pH probe for Bluelab Combo and pH Meters , as well as the Guardian Monitor.The Bluelab Probe replacement (electrode) is suitable for BlueLab products that test the pH of a solution.Unfortunately, Bluelab Probes do not last forever, if they age with normal use they will finally have to be replaced . With good care and good use (after treatment and cleaning once in the month) you can extend the life span .The pH Probe has a double junction reference which provides a longer service life than many other pH-probes and is a gel-filled, non-refillable probe, so in addition to cleaning it is maintenance-freeCompatible with :https://magic-farm.eu/sl/izdelek/bluelab-combo-meter-ph-ec/
