Can anyone recommend to me a decent pH meter that they use? I have been using a Milwaukee MW102 for a year and sadly it does not seem consistent. Drifts all over the place even in buffers. I just sent it in to the factory, they replaced the temp probe and and returned it to me but it still does wierd stuff like this: you calibrate it in 7.01 buffer, then in 4.10 buffer, and if you leave it in the 4.01 buffer, within 1 minute it is reading 3.85 or 3.90.... or if, after calibration, you measure a sample of mash, vinegar or windex, then rinse the probe and put it back into the 4.01 buffer, it can read anywhere from 3.60 to 4.20... but certainly not right around 4.01....
Anyone have a better manufacturer to recommend to me? I'm getting a little fed up with Milwaukee... I'm on the phone with their techs about every brew session lately.... or can anyone tell if I am doing something wrong?
