Page 3: Introduction
1. Introduction to the SBS-2500 The SBS-2500 is a portable measuring instrument suited for determining the density of liquids. The instrument uses the oscillating body method. To fill the measuring cell the built-in sample pump or a syringe may be used. The results are automatically calculated into one of the following units: density, specific gravity, API degrees, Brix, % Alcohol, % H2SO4, Baumé, Plato, Proof or a user-defined unit. -
