Then I guess I should balance things and put my two-cents in for the hydrometer that all the flooded battery manufacturers use.
I tried using a refractometer. Then bumbled around with how to extract a sample from deeper in the cell than on the surface. An eyedropper with a long stem is very fragile. One with a long hose is inconvenient to store. Returned to the Freas.
The EZ RED is a "Wonder Hydrometer" IMHO. 48 units, around 30 wildly different readings. The right choice can yield specific gravity readings to your personal choice - wotta hoot.

I knew Mex would come up with a picture and correct spelling. This is my reference, and yes hydrometer, not hygrometer.
But I still find I get more consistent and quicker results with a refractometer. Every so often I cross correlate with the Freas and every time results are virtually dead on.
