3-in-1 Animal Clinical Refractometer, Measuring Animal's Health Index of Urine Specific Gravity and Serum Protein, Ideal for Veterinary and Pet Owner

Quick and easy: Just need 2-3 drops of solution and a few seconds, you can get accurate readings. And no battery needed. Features automatic temperature compensation: makes it more convenient to use in different temperature. Measuring range: -total serum or plasma protein(SP): 2-14g/dl, - urine specific gravity of dogs（or large animals）: 1.000~1.060RI, - urine specific gravity of cats（or small animals）: 1.000~1.060RI. Triple scales: the left one is for testing urine specific gravity of large animals like dog, the middle one is for testing urine specific gravity of small animals like cat, the right one is for testing serum or plasma protein level for all animals. Animal clinical refractometer for testing the health index of urine specific gravity and serum or plasma protein for animals.
