The Clinical refractometers are designed for clinical usage and intended for both Veterinary and Human. This is unit provides quick and accurate indication of vital fluids levels. It has triple scale that gives Urine Specific Gravity (SG.) Total Serum Protein (SP) and Refractive index(RI). This unit provides veterinarians with quick and accurate indication of vital fluids' levels. Its triple scale reads the Total Serum Protein(SP) and Refractive Index(RI) of dogs and cats. It's FULLY EQUIPPED with ATC(Automatic Temperature Compensation) that automatically adjust itself to correct temperature discrepancies during use. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading.
