I will also vouch for Hanna sucking. I got their $59 meter (the Champ) and went through two within 2 months. It goes out by .3 about every day, and even if you calibrate it every day, it will get to the point where the screw will not turn down and you will never get a true reading. I switched to a TriMeter constant read and its great.
