The Ultimate Answer For Monitoring

Low-Concentration Liquids

 

Digital Differential Refractometer DD-7

This model measures solutions of low concentration up to 2% at an extremely high accuracy level of ±0.005%. It is recommended for such samples as unsweetened tea and surfactants.2 types of solutions – distilled water as the standard solution and the sample liquid to be measured – are injected into the instrument with syringes. By using a standard solution other than distilled water, solutions of higher concentration can also be measured.  

The DD-7 measures solutions of uThe DD-7 measures solutions of up to 2% Brix concentration at thep to 2% Brix concentration at the  extremely high-aextremely high-accuracy level of ccuracy level of ±0.005%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.
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.
