Neptune Systems Solid Surface Leak Detection Probe

* Aquarium leak detection probe compatible with your Neptune Systems Apex Flow Monitoring Module * Upon contact with water, the leak detection probe will send an alert to your Apex system * Place leak detection probe on any solid surface where you want to detect stray water Never miss annoying and potentially damaging leaks again with the Neptune Systems Solid Surface Lead Detection Probe. Plug the probe into your Neptune Systems Fluid Monitoring Module, and when water is detected, the probe will send an alert to your Apex system so that you know immediately. Timing is critical when detecting leaks, so it's common to see two of these flat surface monitors inside the stand, and another two outside the stand, for complete protection against a leaky aquarium. Note: Neptune Systems Solid Surface Leak Detection Probe will only work with the Neptune Systems Fluid Monitoring Module and cannot be used with the ALD module. Directions Simply plug the probe into your Neptune Systems Fluid Monitoring Module and place it on any solid surface underneath your aquarium.
