Magnetic Probe Holder


Magnetic, four spot probe holder.



This is a four spot magnetic probe holder. The holes are big enough to fit regular pH, ORP or other probes along with the thick Neptune Apex temperature probes. The magnets used are pre-coated with a resin making them reef safe as long as the resin is not compromised.

  • Holds up to four probes.
  • Printed out of reef safe PLA.
  • Can fit the thick Neptune Apex temperature probe.

Please read the magnet disclaimer before ordering.

Approx. Size: 5.6″ 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.
