SKU: 800265984264 Categories: , , , , Tags: , , ,


This is a magnetic probe holder for a single probe. The hole is big enough to fit regular pH, ORP or other probes along with the thick Neptune Apex temperature probes. The magnets are pre-coated resin neodymium N50 high strength magnets capable of holding on less than 1/2″ glass (1/2″ will probably work).

  • Holds a single probe, easy to install in tight places.
  • Printed out of reef safe PLA.
  • Can fit the thick Neptune Apex temperature probe.

Please read the magnet disclaimer before ordering.

Approx. Size: 1.4″ x 1.4″ x 1″

* Clear color is essentially PLA with no added color. It’s translucent but not transparent (like glass or acrylic).
** When you choose “Other” as a color, please leave me a message in your order with what you like. Keep in mind that a color that I don’t have in hand will delay the shipping of your order by 2-3 business days so I can get the color in.
