Using the principles of light refraction, ATAGO Clinical Refractometers use special scales for clinical purposes such as specific gravity of urine, and total protein in serum or plasma.
The MASTER-SUR/Nα is designed for clinical purposes: "Serum Protein", "Specific Gravity of Urine" and "Refractive Index". The plastic body model is designed to be resistant salty and acidic samples. It is an Automatic Temperature Compensation (ATC) model with water resistant properties (IP65).
