Anton Paar Alex 500 alcohol and extract meter for beer

Alex 500 from Anton Paar is an alcohol and extract meter for beer that removes the need for external laboratories. The lab-grade analyser determines the beer’s alcohol and extract content, kilojoules, degree of fermentation and other parameters, enabling craft brewers to monitor their entire production from wort to bottle.

The meter uses absorption measurement via NIR spectroscopy and density measurement based on the oscillating U-tube technology. The instrument, which is compact and easy to operate, can be used in two modes. In fermentation monitor mode, it directly displays a fermentation curve, assigned to a tank via sample ID. In the final production stages, it can be switched to its standard mode, to determine a beer’s alcohol content, original or real extract content and other beer parameters.

The meter is claimed to measure alcohol with an accuracy of 0.2% v/v and determine density with an accuracy of 0.001 g/cm³.
