MPR Magnetic Probe Rack
Neptune Systems designed the MPR - Magnetic Probe Rack specifically for the Apex. It will hold the larger diameter temperature probe, pH probe, ORP probe, and salinity probe.
- Made from acrylic and with strong neodymium magnets
- Works securely on sumps and aquariums up to 1/2" thick
Dimensions - 4" long by 2.5" deep with the screws all the way backed out.
Neptune has designed a Magnetic probe rack that will hold up to 4 probes with one hole being slightly over-sized to hold those larger probes like the Neptune temp probe. By simply placing the MPR in your sump or tank, you can now securely hold all your probes in a single spot. If a probe is left loose their is a good chance it may float with the business end being exposed to the air and causing a false reading. The Neptune MPR can work with glass up to 1/2" thick and keep all your probes secure and safe.
Thanks for getting in touch with us in regards to this product. The outside is covered with acrylic and has a thin rubber pad where it touched the glass. I can say that I personally would use the small adhesive clips that come with the MP60 in order to prevent the dry side from falling. Please let me know if there is anything else that we can assist with. Thanks!
I see the are 2 doesn't sizes but it doesn't say what they are.
The inside portion of the probe holder measures 4" across. With the screws backed out as far as they go (so at its thickest) it measures 2.5" inches.
