Keep your critical aquarium monitoring sensors perfectly positioned and safe from damage with the Neptune Systems Magnetic Probe Rack (MPR). Probes that constantly bob around, float to the surface, or sit directly in muddy sump detritus will deliver highly inaccurate readings and fail prematurely.
The MPR solves this by locking your probes firmly in place using a heavy-duty magnetic mounting system. It organizes your testing gear neatly in a single, high-flow zone of your sump to guarantee stable, laboratory-grade telemetry.
📐 Quick Specs
Probe Capacity: Holds up to 4 standard probes simultaneously
Port Configuration: 3x Standard ports (for pH, ORP, Temp, or Conductivity) + 1x Oversized port (designed specifically to fit a larger Apex Lab Grade Temp Probe)
Material Composition: 100% reef-safe, solid acrylic construction with sealed magnets
Glass Thickness Rating: Rated for glass or acrylic sumps up to 1/2" (12mm) thick
Dimensions: Approx. 4" L x 1.75" W x 1" H
