Huh. Also have the pH55 (replaceable electrode, accuracy .1ph, two-point (semi-)automatic calibration, automatic temperature compensation so I wouldn't have to use the old "thermometer and chart" routine lol) for $50 and the pH56 (same as above except resolution to .01pH and accuracy to .05pH) for $64.
Seem really cheap. Hmm.
Uhh. I just figured out that our sponsors probably sell these things too so I guess these last few posts might be disappearing soon. I wasn't thinking.
