The MPR - Magnetic Probe Rack was built specifically for the Apex by Neptune Systems. It can accommodate bigger diameter temperature probes, pH probes, ORP probes, and salinity probes. Made of acrylic and equipped with powerful neodymium magnets Securely holds sumps and aquariums up to 1/2" thick. With the screws fully backed out, the dimensions are 4" long by 2.5" deep. Neptune has built a Magnetic probe rack that can carry up to four probes, with one hole slightly over-sized to accommodate larger probes such as the Neptune temperature probe. You can now securely retain all of your probes in a single location by simply inserting the MPR in your sump or tank.If a probe is left unattended, it may float, exposing the business end to air and resulting in a misleading reading. The Neptune MPR is capable of working with glass up to 1/2" thick while keeping all of your probes secure and protected.
