irrelevant. you mentioned there being a variance of ‘2‘. I test s.g. where the variance is only .002.

Its the same thing for our purposes as hobbyist just a different scale so why argue about it wether you measure in ppt or SG or conductivity. It all amounts to the same thing so what does it matter which you choose?
In fact salinity in ppt is a more accurate representation anyway so why be a smart guy and tell someone else their post is irrelevant.
Its like measuring in celsius, Fahrenheit or Kelvin....its just a different scale.

Caught this thread at the perfect time I was contimplating the milwaukee refractometer against one of the cheaper red sea units. But I guess for the extra 40 bucks it sounds like its worth it. Thanks

Thanks I appreciate it. My last tank I used only a hydrometer and now wonder how I even kept anything alive.I didnt know any better at the time but this time around I wanna make sure I do it right.
Perfectly calm. I just don't see the point of being a wise guy calling someone out telling them their point of view is irrelevant when we are basically talking about the same thing, thus nobodies POV is irrelevant.

Well it sounds like nobody is worried about the Milwaukee's accuracy but I was curious about it so I emailed them. Here's their response.

Concerning your question regarding specifications of accuracy. Every
instrument manufactured by every company all over the world and for every
application have in there specifications a plus or minus (+/- ) "accuracy"
or sometimes referred to as "deviation" or even "accuracy deviation" --
there is no such thing as a perfect instrument. The MA887 refractometer you
have has a plus or minus [ +/- 2 ppt or +/- 2 PSU or +/- 0.002 S.G ] that is
2 parts per thousand or 2 practical salinity units or 2 specific gravity
points at read. Your not going to find any instrument that is any more
accurate than that!

So this is common in lab equipment and what I believe they're saying is each unit could have a deviation but that deviation is consistent. In other words if you test yours and it's correct it's not going to vary from reading to reading. It may have a variation from another MA887.
Mine is correct when tested with calibration fluid and I'm convinced they just give that specification in case they have a production batch that's slightly out of spec..
