Neptune Systems Magnetic Probe Rack

The Neptune Systems Magnetic Probe Rack is an accessory designed to hold probes and sensors (pH, ORP, temperature, etc.) securely in place inside your aquarium or sump. It uses strong magnets and a corrosion-resistant bracket, allowing easy attachment to glass or acrylic walls and quick repositioning without tools. The rack helps keep probes stable and in the correct position for accurate readings, reduces the risk of probe damage or algae buildup around the sensor base, and makes maintenance (like cleaning or calibration) simpler and safer. Because it’s compatible with all standard probe sizes and controllers that use Neptune probes, it’s a useful accessory for anyone running automated monitoring systems.
