Elos OsmoController ATO

The set up of the OSMOCONTROLLER Digital is very simple. It works with most sumps without the need for programming. The unique sensor design has a built in buffer for waves and small changes in the sump that will normally cause a top off system to unnecessarily top off.
  • Electronic Water Level Sensor - NO MOVING PARTS!
  • Very easy setup. (System runs a 5 minutes self-diagnostic test when it is first plugged in.)
  • Maintains a very accurate level, very important in marine systems for a stable salinity level when keeping delicate animals.
  • Requires 3/8" tubing, which is not included
  • Made In Italy
