德国PFEUFFER单宁计（多酚测定仪）

组合了自动恒温控制测量槽，磁力搅拌，浊度计，光度计，数据处理和打印机及添加装置。它适用于测量含有酚类物质的液体，如啤酒、麦汁等。

菜单式操作可精确测定：单宁，敏感蛋白质，还原能力（ MEBAK规定），冷混浊物（MEBAK规定），硫酸铵滴定极限值。

The Tannometer is suitable for testing most clear liquids and those which contain phenols such as beer, wort, extract of brewing barley, malt and hops, grape and apple juice, fruit juices and vegetable extracts. The comprehensive analysis allows
statements regarding good and poor characteristics like sediment formation, colour intensification and taste changes for routine controls. The operation is menu controlled. The automatic modes support the analysis of tannoid content, protein
sensitivity, reducing capacity, chill haze and ammonium sulfate titration limit.

An example of how this instrument could be of benefit to the barley and beer industry:
The concept according to which an equilibrium occurs between protein and tannoids allows us to understand that a wort and the corresponding beer cannot simultaneously be rich in protein and tannoids. The control of these two classes of components gives the brewer precise information about the quality of the raw materials malt and hops. The maltster uses the Tannometer for the purchase of his barley and the control of his production. At the different stages of beer production, rapid
analytical methods allows us to follow the dissolving of tannoids, the precipitation of proteins and the efficiency of stabilisation treatment aimed either at the tannoids or the proteins. Therefore the Tannometer would be a simple way to optimise the
amount of stabilising agent used.
