Neptune LD-3 Optical Multi-Surface Leak Sensor

Neptune LD-3 Optical Multi-Surface Leak Sensor is used to detect water spillage on various surfaces to help prevent potential disasters.

Be alerted of water spillage and take corrective action before disaster strikes

  • Optical sensor technology
  • More reliable than analog counterparts
  • Epoxy-coated and corrosion-resistant
  • Can be reused after contact with water
  • Nonreactive to metallic surfaces-- no more false alarms
  • Multiple applications-- can be placed almost anywhere
  • Weighted to stay flat
  • Connects to FMM port to communicate with Neptune Apex controllers

Neptune's LD-3 Multi-Surface Optical Leak Sensor marks a significant improvement over its analog counterpart, the LD-2 Solid Surface Leak Detection Probe. While the LD-2 utilizes conductive strips to detect fluid leaks on surfaces around your aquarium, the LD-3 takes advantage of optical sensor technology instead. This shift in sensor technology gives the LD-3 two distinct advantages over the LD-2:

Reusable and resistant to corrosion. The LD-3 sensor can be reused after contact with water. Unlike the conductive strips of the LD-2 which are prone to corrosion from contact with saltwater, the LD-3's epoxy-coated optical sensors can continue to provide long-lasting leak detection after repeated contact with saltwater & with no risk of corrosion!

Multi-surface applications with no false alarms. The conductive strips used on the LD-2 can sometimes give a false alarm when placed on metallic surfaces. With its optical sensor, the LD-3 can effectively be used on any hard surface material type, including metal and epoxied cement, without the risk of triggering false alarms.

Looks like engine air filter, it’s smaller than needed; but needs to be compared. Haven’t looked at air cabin yet
