Neptune Systems ApexEL Aquarium Controller

Introducing the new Neptune Systems ApexEL, the "Entry Level" Apex.

Maintain your aquarium with ease.  The ApexEL monitors key parameters like temperature, pH, and the status of your connected equipment.  Proper monitoring helps reduce the risk of losing your aquatic pets from parameter swings or failed equipment.

At a lower cost than its big brother, the Apex, the ApexEL shares almost all the features of the flagship Apex, with the exception that it does not have built-in ORP, salinity monitoring, or 0-10V ports.

The ApexEL is expandable with modules and probes, if desired in the future.
