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

Hi All,

I purchased these water meters in bulk with a bunch of friends who also
have salt water tanks. We have a few left over and I thought I am
offering them to diffrent group members at a discounted price. The JBJ
model of this meter sells for $100+. We are looking to sell them for
$60.

It's a 3 in 1 hand held digital thermometer, salinity, and specific
gravity meter. Take a look at the pictures on the link below.

Here are the Specifics:

Its a 3 in 1 meter
Thermometer 0~100 degrees F
Specific Gravity 1.000~1.032
Salinity 5ppt~40ppt
Automatic Temp. Compensation

Includes calibration fluid, an extra set of batteries, instructions,
and a box to keep it in.

It has definitely helped me to save time maintaining my tank. Let me
know if you're interested, and email me with any questions or comments
to .

Thanks,

J

Interesting e-mail address.

It is obvious that this post is not factual.

What is "interesting" about that e-mail @ qmail, Wayne ??
Haven't you hear about http://gmail.google.com/ before ??

It is obvious that this post is not factual.

Why would such thing be "obvious" based on this e-mail address ??

Don't anyone be buying this meter, you will not be happy. The electronic scale system
built into the meter is a mess. I wrote the manufacture months ago on how to fix it with
all the tech data and proof they would need and no reply

I happened to get one of those about six months ago. The salinity meter
doesn't seem to stay calibrated. I measure my tank about once a month, and
I need to recalibrate it almost every time.

Can you tell me what specific errors you noticed with the device? How did
you suggest that they fix it?

This was my e-mail

This meter is going to be way off. Seawater is not NaCl, it is seawater. Calibration
solutions need to be 53 mS= 35 ppt NSW salinity. A 35 ppt NaCl Salinity calibration
solution will only yield a seawater Salinity of 32.5 ppt NSW Salinity. That means that if
one takes your meter and it reads 35 ppt it is off around +2 points low = about 32.5 ppt
NSW so it needs to read 37.5. This is a nice toy you have but needs some fixing, same with
those tables.

Furthermore, your table is a NSW Density table, set to 59 F.
Density DOES NOT = SG. SG is roughly 1 unit higher, meaning D = 1.023, then SG = 1.024. I
have a Excel spread sheet program that lets me calculate such tables, based on seawater
stds. And all this depends on what the SG meter is calibrated to.

The std solution of a meter for testing seawater is, 32.4536 g/Kg, which = 53,065 uS @25C
or 53 mS. If it is for
SG it is different, if it is for a refract it is different. The only solution that meets
all NSW readings, be it conductivity @53,065 uS (53mS), @ 1.0269 SG,
Refract @ 3.5% or 35 ppt is a real std seawater solution. Such solutions are
available only in one place and cost about $$$ for a 5 l bottle http://www.seawater.com

The std equation of state for seawater is

K15 = Conductivity of seawater sample / conductivity of std KCl solution @ 15 C 1 ATM and
the KCl being at 32.4356gkg

S = 0.0080 - .1692 K15 exp 1/2 + 25.3851 K15 + 14.0941 K15 exp 3/2 - 7.0261 K15 ² + 2.7081
K15 exp 5/2

If the conductivity of the sample is 53, 065 uS and it is the same for the KCL, then K15
=1. If you plug that 1 into the equation it = 35 ppt


Have them look at these

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.

Yes I am familiar with gmail. In fact I also have a gmail
e-mail address. But look at the name before the ".

Also do a goole search for that e-mail address, both on
groups, and web.
