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!
