Neptune Systems MPR Magnetic Probe Rack

Neptune has designed a Magnetic probe rack that will hold up to 4 probes with one hole being slightly oversized to hold those larger probes like the Neptune temp probe.

By simply placing the MPR in your sump or aquarium, you can now securely hold all your probes in a single spot.

If a probe is left loose there 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.
