Density Meters

Oscillating U-tube Technology

The measurement of the density of an aqueous solution can be utilized to identify substances, to determine their quality or purity and to measure their concentration in binary or quasi-binary mixtures. It is a common tool utilized for quality assurance in the pharmaceutical, food & beverage, chemical and petrochemical industries.  A.KRÜSS Optronic Density Meters utilize the highly accurate oscillating U-tube method in combination with controlled temperature for measuring density.

 

Density Meter Options

  • DS7700 Model with an accuracy of +/- 0.001 g/cm3 or DS7800 Model with an accuracy of +/- 0.0001 g/cm3
  • Both models are available in the following sets:
    • Set 1 for manual sample introduction with any degree of viscosity
    • Set 2 for manual sample introduction of aggressive or highly viscous samples
    • Set 3 for semi-automatic sample supply and cleaning. This set comes with a syringe and peristaltic pump
    • Set 4 for automatic sample introduction for high numbers of samples of low to slightly viscous nature. This set comes with syringe, peristaltic pump and autosampler
    • Set 5 for automatic sample supply for high numbers of samples of aggressive nature.
