Anton Paar Alex 500 alcohol and extract meter for beer

Tuesday, 24 February, 2015



An alcohol and extract meter for beer, Alex 500 from Anton Paar, frees craft brewers from the need for external laboratories. The lab-grade analyser determines beer’s alcohol and extract content, calories, degree of fermentation and many more parameters. The meter is based on a combination of technologies, including absorption measurement via NIR spectroscopy and density measurement based on the oscillating U-tube technology.

The compact, easily operated instrument can be used in two modes. In the 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 with lab-grade accuracy. The product measures alcohol with an accuracy of 0.2% v/v and determines density with an accuracy of 0.001 g/cm3.

The device covers the entire beer measuring range, not just part of it. Brewers are provided with direct, real-time results, without the necessity for a separate calculation or distillation. They only need one single instrument and can handle the entire measurement procedure themselves.
