I just started to monitor my PH with a meter that was given to me,its a old SM101 Milwaukee unit( green housing). I bought a new SE220 probe and calibrated it. It seems to hold true in the calibration fluids but fluctuates in the sump.
So I'm thinking it's old so let's upgrade. I see Milwaukee has a new housing and motherboard, Pinpoint has better reviews but the newest review is several years old.
So I come to you to see what most use or likes or dislikes between two.
