yes i do have it. i ordered it from marine depot.
it came with two calibration fluids. you use them with
the probe while using a small screwdriver, which it also
came with, to make sure you are callibrated.
mine came completely calibrated.. but i played with it
anyway till i was satisfied i
saw how it worked.
i then mounted the unit on a shelf after putting batteries in it.
the probe stick in my tank 24 horus a day non stop. it is rather
cool watching as you turn your lights off and the ph slowly goes
down. no guessing! but i have test kits anyway, and they are always
close.
it is a good buy!
i wish the nitrate and the salinity tester were as good.
the reviews on them are awful.
is there any other pinpoint gear that is known to be solid
as a rock like their ph monitor?
takin over the thread!
