BEER TURBIDITY
Beer clarity is a parameter that is constantly monitored in the brewery. Clarity can be affected by haze, an insoluble or semi-soluble particulate matter small enough to form a colloidal suspension in the beer. These particles scatter transmitted light and reduce the clarity of the beer. To ensure beer quality, brewers need more precise electronic equipment than visual inspection.
A number of substances can cause haze in beer, but the most common problem is cross-linking of polyphenols and proteins. These materials exist in equilibrium in the beer and manifest as haze when they combine to form insoluble colloids. There are a number of stabilization treatments available to avoid haze problems, and the product must be controlled at several steps in the brewing process, particularly after filtration and before the beer enters the clarifier.
Measurements are taken from degassed beer samples and results are reported in European Brewery Convention (EBC) units.
CONNECT TO COMPUTER
By RS232 port
DATA LOG
Up to 199 measurements in internal memory and reviewed at any time.
AUTOMATIC CALIBRATION
At 2 or 3 points using separately purchased standard solutions.
AMCO AEPA-1 STANDARD SOLUTION
Recognized by USEPA as primary standard. These non-toxic standards are made from styrene divinylbenzene polymer spheres of uniform size and density. Standard solutions This is reusable and stable with long shelf life.
The HI93124 Portable Haze Meter is based on EBC (European Brewery Convention) units. The EBC unit is ¼ of an FTU unit and the FTU is equal to the NTU unit (Nephelometeric Turbidity Unit). The conversion table between these units of measurement is shown below:
