Due to the modular concept, systems can be custom-tailored like e.g. here a combination of Alcolyzer, density meter, CO2 meter, PFD filling device and the HazeQC turbdidity meter.

Turbidity Measuring Module: HazeQC ME

A solution for the measurement of turbidity in liquids, the HazeQC ME turbidity measuring module, is provided by Anton Paar as part of a modular measuring system. The approved ratio method with measurement at three angles (transmission 0°, scattered light at 25° and 90°) is used to prevent the influence of particle size on the turbidity value. The measurement is carried out at a wavelength of 650 nm ±30 nm (MEBAK- and EBC-compliant) in a cell with adjustable constant temperature. This turbidity measuring module expands Anton Paar's product portfolio and adds a further important parameter for analyzing liquid samples - providing the same high quality expected of Anton Paar products.

Key Features

Accurate and traceable turbidity measurement

  • Three-angle turbidity measurement (transmission 0°, scattered light at 25° and 90°) at 650 nm according to MEBAK and EBC
  • Approved ratio method eliminates the influence of particle size on the turbidity value
  • Highly accurate Peltier-thermostatted cell

Combinations for up to 7 parameters possible

  • Up to 7 parameters in one measuring cycle if used in combination with PBA-B (density, alcohol, beer color, pH, CO2, O2, turbidity)
  • Combination with all Generation M systems, with Alcolyzer Plus Beer, with Alcolyzer Plus Spirits or with the Beer Analyzing System (Alcolyzer Plus Beer, density meter, sample changer)
  • All measurements directly out of the bottle or can, no degassing required if using a PFD Filling Device
