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.
Whats Included?
1x Double Junction Lab Grade ORP probe w/ 10' cord
Note: We suggest calibrating probes every 60-90 days for reliable and stable readings. Calibration fluid sold separately.
Overview
Fewer Clogs. Longer Life.
The double junction design keeps contaminants away from the sensing element, extending calibration intervals and overall probe lifespan in demanding saltwater environments.
Double Junction Design
- Two isolation chambers separate sample water from the reference gel
- Blocks proteins and organics before they reach the sensing element
- Reduces fouling-related drift compared to single-junction probes
Reliable ORP Readings
- Holds calibration longer between service intervals
- Recommended recalibration every 60–90 days under normal reef conditions
- Consistent output supports automated dosing and ozone control decisions
Broad Compatibility
- Standard BNC-style connector works with Neptune Apex and most third-party controllers
- 10-foot cord included for flexible sump or equipment placement
- Direct drop-in replacement for worn single-junction ORP probes
