The cheapo hydrometer that came with my deluxe starter kit is off by .005 units when measured at 60 d F DI high quality H20.
Knowing this, it’s easy to adjust my readings by subtracting .005. I’m happy to do this but it got me thinking. Is the ROI there for lab grade hydrometers or refractometers?
With refractometers I understand that you only need a few drops of sample rather than several mls, but what, if any, are the other advantages?
Thanks for your input.
