Hello all,
Weird question. So basically, I’ve always used a bottle of Fritz Refractometer fluid to calibrate my refractometer. I had a bottle of BRS fluid, and also just got another brand new one. Well today I tried all of them, to find there was a difference of 5ppt between the Fritz and a BRS bottle, and 2ppt between the two BRS bottles. So yikes. I tried setting my Refractometer to zero using RODI, and tested the three bottles; Fritz was 39, and the BRS were 34 and 36ppt. How can I deduce which one is right? I’m worried that my salinity has been way off for a while and I’ve had no idea.
