Apex MPR Magnetic Probe Rack *

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 there is a good chance it may float exposing the business end 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.
