Do you have a digital model for reading the specific gravity of lead acid battery?
The Palm Abbe digital refractometer represents the perfect method for measuring the concentration or specific gravity of the sulfuric acid (H2SO4), or state of charge, in a lead-acid battery. There are several sulfuric acid scales available for the Palm Abbe refractometer including, specific gravity, density, percent by weight. Try our Build-Your-Own section. You can choose up to 5 custom scales!
