ReefSense Magnetic 4-Probe Holder
Keeps every probe at the same depth, every time. The Red Sea ReefSense Magnetic 4-Probe Holder is a magnetic bracket that mounts up to four ReefSense digital probes — pH, ORP, Salinity/Temperature or Temperature — together on the inside of your sump or display, holding each sensor at a consistent depth so readings stay comparable run to run.
Key features
- Holds up to four probes — one bracket for your whole ReefSense set instead of four separate mounts.
- Magnetic mount — no drilling, suckers or brackets glued to acrylic.
- Fits glass up to 12 mm (½") — covers the great majority of display and sump glass thicknesses.
- Consistent probe depth — keeps every sensor at the same position, which matters for repeatable, comparable readings.
- Genuine Red Sea ReefSense accessory — built to the same fit as the probes themselves.

Common questions
Does this come with any probes?
No — it's the mounting bracket only. Probes are sold separately.
How many probes can I mount on it at once?
Up to four ReefSense probes on the one bracket.
Will it hold on my glass?
Yes, up to 12 mm (½") thick — that covers the glass used on the great majority of aquarium and sump walls.
