Double Junction pH Probe

For reliably measuring the pH value.

Neptune System Double Junction pH Probe

pH probe has a BNC-connector

Double junction probes place a second vessel inside the main electrolyte with a second internal junction. The means that even when the aquarium water eventually begins to make its way in the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode.
