Hazetester IV– nephelometer with termostated measuring chamber, precision dosing syringe pump for haze measurement, control of beer stabilization and prediction of beer and other beverages colloidal stability
Abstract
Stand-alone prototype of laboratory device for haze measurement of liquids was innovated. Hazetester works in a nephelometric mode at formazin calibration.
It has display and keyboard, basic functions are controled by a microprocessor unit. There are a syringe dosing pump and a mixer built-in.
Measuring sample chamber is kept at constant temperature (+/- 0.2 oC) by a peltier type thermostat. With the aid of specially developed PC SW MZN Control it is possible to perform nephelometric titration tests (e.g. tannoid content, sensitive protein content, SASPL) for beer stabilization control and prediction of colloidal stability in special vials which enable sample centrifugation directly before test performance.
