Traditional magnetic probe holders haven’t changed much over the years—until now. The MPO Quatro Magnetic Probe Organizer introduces innovative safety and convenience features that set it apart. Designed to work seamlessly with Apex, Hydros, Profilux, and other water monitoring systems, this organizer securely holds four standard probes while eliminating the common risks of rust and corrosion.
Rust-Free & Secure with ModMag Technology
Unlike traditional acrylic probe holders that glue magnets inside, risking leaks and rust contamination, the MPO Quatro uses the ModMag—a double-sealed, ultrasonically welded ABS enclosure that prevents water intrusion. The built-in "Shake-Test" feature allows you to confirm at any time that your magnet remains completely dry and safe.
No More Thumbscrews—Just Slide & Secure
Probes are firmly held in place with the Slide-Loc® silicone gasket system, eliminating the need for fragile thumbscrews that can break, strip, or crack probes. Simply slide your probes in, and they stay put—no adjustments needed.
Designed for Automated Testing & More
The MPO Quatro isn’t just for probes—it also includes two guide tubes for securing automated testing system pickup tubes like those used by the Neptune Systems Trident. This keeps tubing properly positioned, preventing air intake and debris pickup from the sump. The included temperature probe adapter makes it compatible with smaller probes used by many of the popular heater controllers.
