Looking to get a PH probe, I know nothing about them!

I want to add a ph probe but I’m not sure how and i want to know which ph probes you guys have had the most success with? Also just a side question what do you use to test calcium!?

Salifert for kh ca

If you looking for stand alone ph prob pinpoint have a nice stand alone ph prob and monitor.

It looks like it works best with and arduino but I need an analog to digital converter to use it with a raspberry pi. I'll let you know how it turns out.

Milwaukee makes a good, relatively inexpensive pH controller. I’ve been using one for over 15 years, and while the actual probes need replacing regularly, the electronics unit has proven to be quite enduring. The thing I like about the Milwaukee is that the switching plug can, in turn, be connected into something like an apex energy bar for redundant control.
