PH/CO2 Controller

[safety4fire]

I have a MA957 CO2 Regulator, I am in need of a PH/CO2 Controller. I was thinking of getting a Milwaukee SMS122 pH/CO2 controller, are these good controlers? Does anyone have a used one for sale?

The all-in-one Milwaukee CO2 controller is not reliable. Actually I should restate that the bubble counter is very unreliable (many many problems), the solenoid is OK (i've heard of some issues but not very many), the regulator is fine.

I agree totally , the needle valve is brass, and only keeps a steady bubble count for about 6 months. The other one J&L has is stainless steel but you then need a separate bubble counter
