Haffmans OptHaze-i
The In-line Turbidity Meter, type OptHaze-i, measures the scattered light caused by particles and incorporates the latest standards from MEBAK (Mitteleuropäische Brautechnische Analysekommission):
• 90º measuring angle
• Red light 650 ± 30 nm to eliminate most of the effects of color of the beverage
• Formazin calibration standard
Particles smaller than 1 μm, such as proteins, mainly cause the light to be scattered under 90º and are measured with the 90º light detector. Hence, particles larger than 1 μm, such as Diatomaceous Earth, yeast and fruits pulp mainly cause the light to scatter forward. To increase the expressiveness of the turbidity measurement, an additional light detector measures the forward scattered light under a 25º angle.
The turbidity sensor is constructed in accordance with the CE hygienic directive and EHEDG design recommendations. It is easily mounted in a Varivent® process connection and executed as a smart sensor, ready to use, calibrated in a range of 0 to 20 EBC.
Application
• In-line, at critical locations in the production line where the determination
of turbidity of beverages is required
