Wrenches,

Looking for advice on digital electrolyte refractometers for testing lead acid specific gravity.
I have never used a digital refractometer. Only the old school refractometers that are not that easy to read accurately.

Digital units vary tremendously in price. And I'm wondering how difficult it is to clean/neutralize the chamber where the electrolyte drops go? I need to test multiple cells and get accurate readings on every cell.

Has anybody here used one of these, and can you share advice on this topic?
