Continuously monitors the function of the water softening unit and protects downstream systems from hardness breakthrough without the use of chemicals.The flow cell is made of PP and is free of non-ferrous metal. The floating contact is used to switch the downstream reverse osmosis unit off, for instance if hard water enters the system. The LED of the optional control unit signals that there is a fault with the residual hardness monitor.
Like the stand-alone unit, but without its own controller. The monitor is connected to the reverse osmosis system. A hardness breakthrough will cause the system to shut down automatically.
