Ph controller what one to get?

[Jellymeat]

I have a co2 system but i want to get a ph controller for it.

I have been looking at the milwaukee sms122.

Has anyone used or owned it before?

And are you able to buy the probe here, or will a generic one work?

or are there any others that are good?

I will most likely be getting it of amazon.

And how do i get it to work with a timer as well.

thanks for the help
