Monitoring Salinity in 2 separate sumps

Hi there,
I have a requirement to monitor salinity in 2 separate sumps, that are separate systems and will have different temperatures.
I have a P4 ultimate set.
What will I need to additionally purchase to do this?
Will I need to set up something in the controller that shows it as a separate Tank?
Given the temperature will be different, how do I link my 2nd salinity probe with the 2nd temperature probe so calculations are correct?

Hi,

you would need expansion cards or an Expansion Box for connecting the additional sensors.
There is no possibility to clearly separate the sensors to 2 aquariums, but you can add descriptions to the sensors.

You can select the temperature sensor for compensation while calibrating the salinity sensor or at the sensor settings 'Temperature compensation'.
