Multiple Inputs
The RKM-SL2 has a variety of input ports providing a broad range of monitoring options. It's a powerful addition to either a ReefKeeper Elite or the ReefKeeper Lite system!
1 x pH port
The pH port on the SL2 is an isolated pH port. This all but eliminates the affect ground loops and system interference when using multiple pH probes. Any standard pH probe with a BNC interface should work with the SL2.
1 x Salinity port
The salinity port uses the DA Salinity probe on this completely isolated port. The SL2 salinity port reports back salinity in PPT.
1 x Temperature Probe port
Digital Aquatics Temperature Probe
2 x Switch ports
The switch ports can be use with float switches or other contact devices to run Auto Top Off (ATO) systems, or trigger other custom events.
Upgradeability
The SL2 also has upgradeable firmware so you can take advantage of our developing feature set; and firmware updates are always free!
