I currently use the following hardware for my c02:
SMS 122 Ph meter with probe.
Milwaukee MA 957 regulator. Includes bubble counter and solenoid connected to regulator. Meter is hooked to solenoid to turn off at a set PH.
So, have had good luck with them (>5 yrs), but want to replace the regulator, counter, and solenoid to a better one as I am starting to see some issues where I have to watch the flow rate more......
Price is not an issue (no gold plating though), so would like to hear some recommendations.
Do people still use the solenoids?
I use a 4 kh drop checker, the meter is just informational and to shut off in case of c02 dump/reg failure.
Mfg and model is good enough. I can web research from that point.
I would like to keep my PH meter with the new reg.
Is for a 180 gal tank...........using either a 5 or 10 lb bottle.
Thanks in advance.
