refractometer help

where can i get the saltwater solution pre-mixed saltwater
to 1.024 or .026 for proper refractometer calibration, and what is it called? brand name? i recalibrated my refactomoter with RO-DI and it seemed to put it farther off then when it came from the out of the box.

It is made by American Marine/Pinpoint and many places sell it:

That should be 1.025

That isn't the fastest link....

Try this one:

FWIW, The fine Dr's got the units of measure wrong on it as it is 53 mS/cm, not 53 uS/cm.

FWIW, it has a sg of 1.0264

Ahh, You are more then likely correct. I was aiming for 1.025 SG in the tank and this was very close.
