AMI pH meters, I just checked mine out, between each number there
are 4 little lines, which if I interpret that correctly that means a .2
difference
There is enough space between the little lines so I can interpolate
.2, .25 .3 .35 and .4 for example.
Operation, Wet soil, wipe probe, insert into soil, rotate back and forth
a 1/2 doz. times, wait one min. read scale. Remove probe and
wipe off.
Price under $20.
Close enough for me.
