The Red Sea ReefSense Magnetic 4-Probe Holder provides a secure and organized mounting solution for up to four aquarium monitoring probes.

Designed for installation in a sump or aquarium filtration chamber, the holder keeps probes positioned vertically and at a consistent water depth while preventing them from moving freely among pumps, tubing and other equipment. Properly securing probes helps protect delicate sensor tips and supports more consistent parameter monitoring.

The magnetic mounting system allows the holder to be installed without permanently modifying the sump. Its position can be adjusted as needed for cleaning, calibration or changes to the filtration layout.

Key Features

  • Securely holds up to four aquarium probes
  • Magnetic mounting system
  • Suitable for glass or acrylic panels up to 12 mm / 1/2 inch thick
  • Keeps probes upright and properly organized
  • Helps maintain a consistent probe depth
  • Reduces movement caused by water flow
  • Helps protect probes from contact with pumps and other equipment
  • Allows easy probe removal for cleaning and calibration
  • Adjustable positioning without permanent installation
  • Designed to complement Red Sea ReefSense probes and the ReefControl system

Compatible Applications

The holder can be used to organize compatible monitoring probes such as:

  • ReefSense pH and Temperature Probe
  • ReefSense Salinity and Temperature Probe
  • ReefSense ORP Probe
  • ReefSense Digital Temperature Probe

Probe diameter and fit should be confirmed when using probes from other manufacturers.

Installation

Place the internal probe-holder section in the desired location inside the sump and align the external magnet on the opposite side of the glass or acrylic panel. Insert the probes into the available openings and position their sensing ends at the appropriate water depth.

Install the holder in an area where the probes will remain continuously submerged and receive representative water flow. Avoid positioning probes directly beside electrical motors, dosing outlets, air bubbles or areas where the water level may fall below the sensing ends.

  • Probe capacity: Up to 4 probes
  • Mounting method: Magnetic
  • Maximum panel thickness: 12 mm / 1/2 inch
