extremely high-accuracy level of

(Note that the range of measurement gets narrower at concentrations higher than 10% Brix.) When a reference solution of 8.000% Brix is used, for
example, the DD-7 can measure concentrations in the range of 8% to 10% Brix at resolution of 0.001% Brix and precision of measurement of
±0.005% Brix. Note: High viscosity samples may not be suitable for measurement.

±0.005% Brix.

• Measurement is very simple. Inject a reference solution and a sample solution to respective injection ports,
and press the Start Switch.

• Digital readings eliminate reading errors resulting from user subjectivity.

Measurement data can be exported to a printer or computer via RS-232C connection.

•

Measure low-concentration food and
beverages, such as coffee, tea, diet sodas,
and herbal extracts.
