FYI, I ordered the pH55 'Martini' and it works like a champ. I calibrate it every couple of weeks and most of the time it is still good, or off by only .1 (im in soil, so...). I did need to calibrate one time more often than stated above, but that was w/in the first week of buying it. Most instructions state that it takes some usage to 'break-in' the probe.KEEP THE PROBE MOIST WITH storing solution!(or 4.0 or 7.0)
I too just got one from eseasongear . (milwaukee PH51) and i do have to calibrate every single use ? i dont understand
i guess all pens are like this?
is it from shaking it to get excess water off it?
Do we HAVE to spend 130 or more for one that stays calibrated or are they all like this?
please and thank u.
Also, if anyone is looking for a sweet ass TDS/EC meter for a reasonable price: HM Digital COM-100 is fast, accurate, and reliable.
Cheers!
