New DR7000 series digital refractometer, model DR7100-P

Digital refractometer nD ranges 1,3000-1,5800; 0-95 %Brix. The new DR7000 series are designed to determine refractive index, Brix percentage and other concentrations in liquid samples. Equipped with a CCD optical sensor, Peltier temperature control, electronic measurement and evaluation systems and a touch screen, they have all the essential elements to ensure accurate and reliable measurements. Operation is carried out directly on the device itself, without the need for a separate PC with additional software. These devices, together with their firmware, comply with all the standards required in the areas regulated by the FDA (depending on the model), as well as by the European (Ph. Eur.) and American (USP) pharmacopoeia. In particular, the DR7200-P and DR7400-P models are designed to meet the requirements set forth in CFR21 Part 11. Features
