Keep your aquarium probes securely positioned

Reliable aquarium monitoring starts with probes that remain securely positioned in the water. This Reef Probe Holder keeps up to four monitoring probes organised and prevents them from moving freely around your sump.

Each opening has its own adjustable locking knob, allowing the probes to be secured individually at the required depth. The open design maintains water contact around the sensors while helping you keep the probes and their cables neatly organised.

Why choose this Reef Probe Holder?

• Holds up to four probes — organise multiple monitoring sensors in one compact holder.
• Individually adjustable locking knobs — secure each probe separately at the required depth.
• Stable probe positioning — helps prevent unwanted movement that can affect consistent monitoring.
• Open design — allows water to flow freely around the probes.
• Improved cable organisation — keeps probe cables together and easier to manage.
• Broad compatibility — suitable for pH, temperature, ORP, salinity and most standard aquarium probes.
• Reef-safe PETG construction — durable and suitable for continuous use around a marine aquarium.

Suitable probe types

The holder can be used with many common aquarium monitoring probes, including:

• pH probes
• Temperature probes
• ORP probes
• Salinity or conductivity probes

Probe dimensions can vary between manufacturers. Check the diameter of your probes before ordering if you use an uncommon or oversized model.
