Neptune Systems Dosing and Fluid Metering System (DOS)


The DŌS is a multi-purpose Dosing and Fluid Metering System. The DŌS connects to any Apex via its AquaBus connection.  The true versatility and functionality of the DŌS comes to life via the software wizards built into Apex Fusion.  This takes dosing to a whole new level in terms of ease of use as well as functionality when compared to standalone dosing systems because the DŌS is part of your Apex ecosystem. Not only can you integrate it into other operations and devices you have configured, but we also will be continuing to expand on its capabilities as time goes on via software updates to Apex Fusion.

The Neptune DOS pairs well with the Neptune DDR to provide a fully controllable and monitorable experience
