Neptune Systems LD-2 Solid Surface Leak Detection Probe

Long-life Temperature Probe - replace your Temperature Probe, add one for another tank, or put one on your PM2/PM3 module for temperature compensated readings.

Double junction probes place a second vessel inside the main electrolyte with a second internal junction. The means that even when the aquarium water eventually begins to make its way in the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode.

The Neptune LLS is a first of its kind industry exclusive! While most liquid level sensors simply measure the presence or absence of liquid at a predetermined  sensor height, the LLS is one continuous vertical sensor that can identify the exact depth of a liquid in both inches and centimeters at any given time. This increased sensitivity in measurement can help you identify and be alerted of changes in evaporation, consumption, and dosing levels within sumps, ATO reservoirs, AIO tanks, dosing containers, mixing stations, and more.

Be notified if there is ever a leak before it turns into a disaster. Connecting the LD-1 Leak Detector to the FMM module will allow your Apex Controller to notify you if water ever touches the sensor. There are many applications for leak detectors from water on floor warnings, skimmer cup overflows and much more.
