  • Apex Display Module - 3.40" L x 4.05" H x 0.65" W

The sleek and compact Apex Display module offers an alternative way for you to interact with the Apex and control nearly every aspect of your aquarium.

MECHANICAL, NOT MEMBRANE KEYPAD The Display Module uses high-quality, mechanical buttons. So what, you say? Well, many devices out there make use of what are called capacitive touch pads. This type of membrane button is just fine for your toaster oven, but in a saltwater environment it is highly susceptible to failure. So, even though the cost was higher, Neptune Systems went with mechanical buttons for their Display Module ensuring your product a much longer life.

Inside the Apex Display Module is a tiny speaker with a big heart. This speaker will play one of many alarm sounds and tunes that are built into the Apex. These alarms are perfect to alert you of a water leak, over temp, or whatever you condition you desire to program into the Apex.

While some may tout the importance of a color display, Neptune Systems disagree. They believe the most important thing for customers is ease in readability and size of the display. What good is a color display if it is barely larger than a postage stamp? That is why Neptune Systems went with the backlit graphical display. It is the perfect match of function and value for customers.

With the Apex Display Module you are not limited to having just one control panel. With the Apex (as an option) you can add one, two, even three control panels all to the same Apex. And, these are not watered down, smaller versions of the main control panel, all modules will have the same display and functionality.
