GHL wifi mini set and GHL accessories?

[Zpmada]

Hi


I am considering a GHL wifi mini but I understand that it only has a pH probe and Temp probe.


Does the KH director measure Alkalinity and can I use that to get alkalinity reading with a wifi mini?


How about the trace elements with an ion director? Can I get calcium, magnesium, etc readings with an Ion Director on a wifi mini?


Finally, is it at all possible to add something to get salinity readings with a wifi mini?


I love the wifi minis compact size but would like to expand its capabilities. Is that possible with accessories?


Thanks!

Adam
