Designed for dogs and cats but can still be used to measure other small & large animals, like sheep or horse, etc.With this refractometer, you can: Do a quick & affordable test for animal health index without high cost laboratory analysis.
Normal urine specific gravity range: Cats; 1.001-1.080 S.G. Dogs: 1.001-1.065 S.G.
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.
Measuring range: total serum or plasma protein(SP): 2-14g/dl, urine specific gravity of dogs（or large animals）: 1.000-1.060 RI, urine specific gravity of cats(or small animals): 1.000-1.060RI

Notice:
1.Accurate measurement based on good calibration, please calibrate the refractometer before your first use. But you don't have to calibrate it frequently, once every a few months is OK.
2.When you put your sample to be tested on the daylight plate, make sure the liquid spreads across the entire surface of the prism without air bubbles or dry spots.
3.Clean the instrument with a soft cloth after each use, keep the refractometer dry and clean, which will keep the instrument accurate and durable. Do not put the entire instrument into water to wash, this may lead the
refractometer to be foggy or rusty inside.
4.Please do not loose any connection part, and don't dropping, colliding, shaking the instrument intensely.
