Product Questions

Can i get the complete dimensions. Need to know if this is going to fit in my biocube. I need the Length across and the width when the screws are clear of the holes. Thank you
Question by: Joseph on Jul 30, 2014 1:31:00 PM
Hi Joseph,
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.

Could this be used to hold tubing in place, like from a reactor or doser?
Question by: Corey McMullen on Jun 5, 2017 8:31:00 PM
While not specifically designed for this purpose, the thumbscrews do allow you to tighten them pretty far down, and would probably work fine for this purpose. Another alternative that we have found to work very well for this is the Bubble Magus Tube Holder Bracket.

What are the sizes of the probe holes?

I see the are 2 doesn't sizes but it doesn't say what they are.
Question by: Allen Ford on Jan 19, 2017 8:47:00 PM
Great question! There are three holes that fit the standard pH, salinity and ORP probes and there is one larger hole that fits the Neptune Apex temperature probe. The standard probe holes are 0.5" and the temp probe hole is 0.65" :-)

Thanks!

Full Details

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.

  • Super Strong By Patrick Em on 8/27/2017

    Holds all my apex probes and keeps them in place. Makes everything nice and organized.
  • Magnetic Probe Rack MPR - Neptune Systems By vapor160 on 8/25/2017

    decided to splurge on this item when I got my Apex system. Very glad I did. works slick and keeps all the probes nice and neat and in one place. no more fishing around in the sump to find one that some how worked its way into a place I didn't want it.
  • These have worked fine for me By Randall on 8/10/2017

    I've got three of these holders in my sump; one for probes, one for two-part, and a third in a different location for trace and vitamin additives. (Actually 4; the magnetic holder for the Apex ATK is the same.) They work great, very solid hold, won't move if you accidentally bump them gently. I agree with the other comment that the screw can get to be hard to turn, especially once they've been wet for awhile or if they become encrusted; just get a very short phillips head screwdriver and problem solved.
  • Magnetic Probe Rack MPR - Neptune Systems By vapor160 on 7/21/2017

    worked like a charm. keeps everything nice and neat and in place. if you are going to spend the money on the probes, why not keep them secure in your tank.
  • Quality and Functionality By jpitch on 5/21/2017

    Couldn't ask for a better product
  • Nice but with a flaw. By Jim on 5/11/2017

    The rack fits nicely in my sump and the individual probes fit as noted. My problem is that the thumb screws are very tight. I need a wrench to tighten a couple. Otherwise it's a nice attractive probe holder.
  • Magnetic Probe Rack MPR - Neptune Systems By vapor160 on 4/11/2017

    This is a nice little handy addition. organizes all the probes and helps keep them where I can reach them for easy upkeep.
  • Love it By Boo on 4/5/2017

    You gotta have it if you have an apex, strong, keep probes and wire organized and neat, nice looking thing in your sump.
  • Super strong! By Lisa on 2/9/2017

    Super strong magnet. Holds all my probes well.
  • Great product By Bob on 2/9/2017

    Great product. Keeps things looking neat and organized.
  • Too Bad it Does Come in Black By Jason on 1/16/2017

    Holds apex probes in a fixed spot to prevent issues. It is recommended that the probes are not placed underwater, therefore this is important. I placed this at the top corner of the tank, so it is out of the way. Only issue is the apex temp sensor has to put in connector first as the end of the sensor will not go through the opening.
  • It works great By Brian on 12/17/2016

    It plastic, its a magnet, it does exactly what it describes. Looks nice too for something I never look at in my sump!
