    In your final production stages, you can switch Alex 500 to its standard mode, to determine your beer's alcohol content, original or real extract content and all your other common beer parameters, like calories, degree of fermentation and many more, with lab-grade accuracy.
    Anton Paar is the world's leading provider of density and alcohol measurement solutions for beer. Alex 500 is the result of decades of expertise boiled down to meet the craft brewers' exact needs.
    In the fermentation monitor mode, the instrument directly displays a fermentation curve for you, assigned to a tank via sample ID.

Alcohol and extract meter: Alex 500

Determines the alcohol and extract content in beer, wine, cider, spirits, liqueurs, and sake.

Alex 500 is a compact alcohol and extract meter that frees craft beverage producers from the need for external laboratories. Besides alcohol and extract content it determines related parameters, such as calories or degree of fermentation, at any time. Alex 500 accurately measures all of your samples, in all production steps, from your juice, wort, or mash to the fermentation process and blending procedure to your bottled product. You can swiftly react to all undesired deviations as soon as they occur. With this lab-grade analyzer under your own roof you can always be sure that your bottles contain what their labels say, in order to keep your customer promise.
