Atago Digital Differential Refractometer DD-7

Atago Digital Differential Refractometer DD-7

Product Description

The Atago Digital Differential Refractometer DD-7 is a precision instrument designed for measuring the refractive index of low-concentration solutions with exceptional accuracy. This device is particularly useful for analyzing unsweetened beverages, surfactants, and other solutions with minimal solute concentration. The DD-7 employs a differential optical refraction method, which allows it to provide precise readings by comparing the refractive index of a sample liquid against a standard reference, typically distilled water. By using a reference solution other than distilled water, the DD-7 can also measure solutions with higher concentrations. Equipped with an efficient heating system, the instrument ensures stable temperature control during measurements.
