Caution for anyone using a refractometer

[Doo]

I think you need to be a Chemist to put that together!

The other solution, will it work on all Refractometers or justthe PINPOINT ones??

Can you buy this stuff at a LPS?

The problem is that a lot of the refractometers that find their way into the aquarium industry are for measuring brine, as in for the pickling industry. Our salt water has a lot of other major elements that also effect the refractive index of the water.

According to Pinpoint, their calibration fluid also works well to calibrate our refractometers.

Here's the original thread that spawned Randy's article.

So after reading this I decided to get some

PINPOINT™ Salinity Calibration Fluid
53.0 mS standardized fluid for calibrating the PINPOINT Salinity Monitor™ with conversion chart

The only catch is I got it from ebay and it did not come with a conversion chart

did I even get the right stuff?

What do I do now - or how do I even use it?

Any help would be great!

I think I found what I am looking for, but any feedback is appreciated
