MISCO Refractometer Q&A Forum

Which hand-held digital refractometer would be best for checking specific gravity of industrial battery electrolyte (sulfuric acid and water)? Need a minimum range of 1.100 to 1.350.

The Palm Abbe digital handheld refractometer is the best choice for measuring the specific gravity sulfuric acid based battery electrolyte. The range for the specific gravity scale (D20/20) for this refractometer is from 1.000 to 1.501 so it should more than cover your range of interest.

I have a model 10440 Refractometer. My question is what reading should i get for lead-acid batteries at full charge? I currently am reading from 16 to 26 on two different batteries.

The MISCO 10440VP is a great refractometer for testing the concentration of metalworking fluids but it is the wrong instrument for measuring state of charge of lead-acid batteries.

A better choice would be either the MISCO 7084VP+ Glycol and Battery Tester, a handheld traditional analog refractometer with a scale for reading the specific gravity of battery electrolyte, or, the Palm Abbe digital refractometer with scales for sulfuric acid concentration.

There are several sulfuric acid scales available for the Palm Abbe refractometer including, specific gravity, density, and percent by weight. The range for the specific gravity scale (D20/20) for the MISCO 7084VP+ is 1.00 to 1.400 and the range for the Palm Abbe digital refractometer is from 1.000 to 1.501. The Palm Abbe is an order of magnitude more accurate than the 7084VP+.

Could I use a Refractometer to measure the density of flooded batteries. Density is 1.200-1.260?

We have two great tools for measuring the density of battery electrolyte in flooded batteries. The first is the MISCO 7084VP+ Glycol and Battery Tester. The 7084VP+ is a traditional analog refractometer with a scale for the specific gravity of sulfuric acid from 1.000 to 1.400. There are also a number of scales available for the MISCO Palm Abbe digital refractometer that can measure sulfuric acid density, specific gravity, concentration (% by weight) well beyond your range of interest.

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.
