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.

Nicely made.
Size: X-Large, Color: Indigo
This is a nicely made jacket. Several people have commented on how they like the coloration. My only complaint is that it is a bit smaller than advertised. I normally wear XL jackets and shirts, however, this jacket fits very tight. I would recommend getting one size larger than what you normally wear.
