Oxygen Measurement Technologies in the Brewing Industry

As all major oxygen analyser suppliers have released an improved version of their existing products or launched a new product based on optical technology over the past 2 years, we thought it would be an appropriate time to review the existing technologies from a critical and objective viewpoint. Based on the oxygen measurement experience amassed by ORBISPHERE over 40 years in the brewing industry, and in both amperometric and optical technologies, we have evaluated the advantages and drawbacks of the most common oxygen sensors from the point of view of brewer?s needs. Critical aspects such as response time, long-term stability, and process condition effects are discussed as well as the benefits of the latest development on the oxygen optical sensors.
