• Animal & Human clinical refractometer 3-in-1 testing of Serum protein, Urine specific gravity, and Refractive index
  • MEASURING RANGE: Serum protein: 0 ~ 12 g/100 ml ; Urine specific gravity: 1.000 ~ 1.050 ; Refractive index: 1.333 ~1.360 RI
  • MEASUREMENT ACCURACY: Serum protein: ±0.2 g/100ml ; Urine specific gravity: ±0.005 ; Refractive index: ±0.0005 RI
  • Auto Temperature Compensation (ATC), rest easy that your measurements are always accurate regardless of temperature variation
  • Cushioned w/ soft and comfortable non-slip rubberized grip, insulate test solution from body heat

Purchased for my vet clinic and works just as well as expensive ones
