Aqua Medic Electrode Holder
Keep pH and mV probes at a fixed, repeatable depth instead of drifting around the sump. The Aqua Medic Electrode Holder mounts on the aquarium or sump and holds two or four electrodes at a fully adjustable depth, so every reading comes from the same spot in the water column instead of wherever the probe cable happened to settle.
Key features
- Two sizes – Holder 2 takes up to two electrodes, Holder 4 takes up to four, for setups running separate pH, ORP, temperature or other probes.
- Adjustable submergence depth – set and keep each electrode at a consistent depth for repeatable, comparable readings over time.
- Simple aquarium or sump mounting – attaches directly to the tank or sump edge without extra hardware.
Specifications
| Model | Electrode capacity | Manufacturer part number |

| Holder 2 | Up to 2 electrodes | 230.62 |
| Holder 4 | Up to 4 electrodes | 230.64 |
Aqua Medic doesn't publish electrode diameter compatibility, material, or exact dimensions for this accessory.
Suitable for, and not suitable for
- Suitable for mounting standard aquarium pH, ORP/mV, temperature and similar probe electrodes at a fixed depth in a display tank or sump.
- Not suitable as an electrode itself – this is a mounting bracket only and doesn't include probes, controllers or cabling.
Care and maintenance
Rinse the holder periodically to keep the electrode channels free of salt creep and algae, which can otherwise shift an electrode's depth over time and skew readings.
Goes well with
Pairs with Aqua Medic pH, ORP and temperature probes, and with controllers that use those probe types.
Warranty and delivery
Covered by Aqua Medic's manufacturer warranty, in addition to your rights under Australian Consumer Law. Standard freight.
Common questions
Do I need Holder 4 if I only run two probes now?
Only if you plan to add more – Holder 2 is lighter and less bulky if two electrodes is all you'll ever run; Holder 4 leaves room to expand later.
Will it fit any brand of electrode?
Aqua Medic doesn't publish a compatible electrode diameter, so if you're mixing brands, check physical fit before ordering rather than assuming universal compatibility.
Can I adjust each electrode to a different depth?
Yes – submergence depth is adjustable per electrode, so probes measuring different parameters can each sit where they read most accurately.
