  A Hort Science report of some years ago found the cheap pH meters were
useless. I do not know anything about the quality available to day. I
measure pHs many times perday and would be in big legal troubles unless
I calibrated with NBS buffers every day. Those will cost you $20 per
year. If the meter does not have a way to adjust the meter reading to
agree with the known value of the standard buffer, you know it is just a
gadget and not a meter.
