Add this to your Reefkeper Elite or Lite and you get separate PH and Salinity ports plus additional temp and switch ports. The unit will be selling for $80 from DA and should be available in September. Includes the module, 6 ft Bus cable and mounting screws. Sorry, not supported by the RK1 and 2.
The RKM-SL2 is the newest System Lab module from Digital Aquatics. It’s a big leap forward with fully (and individually,) isolated PH and salinity ports.
The SL2 also allows for another temperature probe to be added to the system for redundant monitoring as well as two more switch inputs; great for ATO systems or leak detectors.
