Measure serum protein, specific gravity of urine, and refractive index – with one instrument!
Use these refractometers to provide precise and accurate readings for urine specific gravity, serum protein, and refractive index. Units feature a rugged, high impact plastic design that is corrosion resistant. The large easy-to-read display is screen shaded and the rubber eye guard allows you to comfortably take your measurements. Read your measurements in seconds after placing only a few drops of sample on the prism.
