Digi Mate 3in1 Meter Temperature/ Specific Gravity Meter/Salinity Meter

I never had a meter, a guy on our chem from was asking about one. I looked at the
instruction manual and its operation. The meter is calibrated using table salt. Table salt
is not seawater when dealing with EC meters. Density is also not SG. That table may be a
NaCl SG or a NaCl density table. It is not a seawater table of any kind.

Their 5-40 ppt is not seawater salinity it is NaCl or table salt salinity and they are
not the same. When the meter is calibrated by their means, 35ppt on their meter is not 35
ppt NSW but 33. 5 NSW . The Sg on that meter is also useless.


You calibrate that meter ? With what, table salt, correct, NaCl , that is not = to the
salt in seawater buy a long shot.

Well they may not be happy if they knew there salinity and SG is low. Is it that far off,
no but it is not doing as claimed. You can fix that meter if you want . Get a PinPoint 53
mS calibration solution and adjust the meter so it reads 35 ppt....fixed. That SG will
still be useless. You should be able to see that if you flip the switch to SG once
calibrated correctly to NSW. I will not say 1.026 NSW SG

: Hi Boomer,
:
: It is strange that you have not heard back from the manufacture. Where
: did you get your meter from? We had a problem with one of the meters in
: the group. We returned it, and got it replaced with a new one pretty
: quickly.
:
: I use this meter only now. I live near a huge LFS that is very popular
: for deliveries. They use it in all their tanks now. I have heard some
: problems here and there with this meter but for the most part people
: have been pretty happy with this meter. Sounds like maybe you recieved
: a bad one. I have only had to calibrate mine every month or so.
