| DD-7 Digital Differential Refractometer |
 |
|
| The Ultimate Answer For Monitoring Low-Concentration Liquids |
High-accuracy measurement is made possible by measuring the difference in concentrations of 2 solutions.
The DD-7 measures solutions of
up to 2% Brix concentration at
the extremely high-accuracy level
of ±0.005% Brix. |
 |
| (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. |
- 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 other herbal extracts. |
|
Measure concentrations of sanitizers and
disinfectants, such as hydrogen peroxide
solutions, at a precision level of ±0.012%
or higher. |
|
Measure surfactants, anti-rust agents,
metal-working fluids and other industrial
solutions at ±0.005% Brix accuracy. |
