Last longer
Require less frequent calibrations
Are more accurate than single junction probes. Single junction probes put the reference electrode in direct contact with aquarium water.
Over time, the junction will slowly leak aquarium water into the electrolyte which changes the accuracy of the probe and requires more frequent calibrations.
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. Compatible with all Apex Systems and PM1 modules.

Neptune Double Junction probes will out last most other traditional lab grade probes letting you go longer between calibrations, and having to purchase and replace probes less frequently. The Double Junction isolates the reference gel and probe from proteins and other organics that may otherwise precipitate and clog, shortening the lifespan of the probe.
-Longer lasting
– Reliable readings
– Quality connections
– BNC style connector
– Calibration solutions sold separately
Neptune’s Double Junction ORP Probe is compatible with any monitor or controller with a BNC style connection. If you just need to replace your worn out probe or add another you will not be disappointed with the double junction feature of these probes. Most probes have a single chamber to house the actual reference probe and fluid that can become contaminated quickly throwing off readings and requiring calibration quite often. The double junction probes have two chambers that keeps any contaminants that could possibly react with and clog the actual sensing portion of the probe.
