Preserve CO₂ When Purging Beer Tanks With the Mettler Toledo InTap Portable Dissolved Oxygen Analyzer

A craft brewer uses CO₂ to purge oxygen from the headspace in bright beer tanks to reduce dissolved oxygen levels in final products. They used a time-based method to determine when to determine purge completion, but this is an imprecise method that can overuse expensive CO₂. METTLER TOLEDO provided the InTap portable oxygen analyzer to the craft brewer. InTap measures dissolved oxygen levels down to 2 ppb using a highly precise optical sensor, making it suitable for a wide range of brewery applications ranging from purging to monitoring filling lines.

This video discusses how a craft brewer reduced CO2 use with a convenient, portable oxygen meter.

It addresses critical issues concerning beer production, such as: 

  • Complete tank purge determination.
  • Why use a portable meter to measure dissolved oxygen? 
  • How to Increase Your Product Quality Confidence

Brewers, Make Oxygen More Your Friend, and Less Your Enemy. Check Out the Mettler Toledo InTap™ Portable Optical DO analyzer

Brewers have a complicated relationship with oxygen. 


At times oxygen is your friend. It's needed for barley germination. It's needed to synthesize fatty acids and sterols in yeast. And it improves colloidal stability. 

Oxygen is also one of the the brewers worst enemies. It has a significant effect on color. It lowers the  rate of wort separation. It can cause undesirable flavors. And is causes haze and makes finished beer stale.

By the way, we're talking about the dissolved oxygen (DO) in solution here. Not the external oxygen the water, wort, or beer tank headspace.

Fortunately Mettler Toledo provides instrumentation to assist brewers in they management of oxygen. Their InTap™ DO analyzer with optical technology, is both a portable measurement tool and a convenient calibration instrument. It facilitates measurement and calibration procedures in both process and laboratory settings, and reduces the risk of operator error.

The InTap™ portable oDO analyzer is a portable measurement device for dissolved oxygen
measurement and for calibration and data logging of optical dissolved oxygen ISM® sensors
(InPro® 6970i) installed in the process. The InTap™ and the sensors communicate via Bluetooth.

Measurement point tracking in the InTap™ portable dissolved oxygen meter allows operators to easily connect stored measurement data to different locations in production, making it easy to maintain records point-by-point for traceability and documentation purposes.

Reliable optical dissolved oxygen (DO) sensor technology is also available in the InTap™ portable meter for spot check and reference measurements. With Blue- tooth communication, hassle-free calibration of in-line DO sensors is done quickly and easily.

Analytical Measurement Solutions for Optimization of Your Brewing Process

Brewing Stage Diagram
Stages of brewing and areas for process measurement.
The beer market is currently experiencing an intense globalization process, reflected in escalating competitive and cost pressures. In addition to this, there is growing diversification into new, innovative beverages that demand maximum production flexibility. The time to market is becoming ever shorter, and product quality has to be guaranteed at a consistently high level, accompanied by an increase in productivity.

In-line Measurements in the Brew House

Proper process control plays a vital role in determining the flavor, foam stability, and color of the finished beer. The relative measurement sensors are exposed to high temperatures, and solid particles and turbidity constituents, and must be capable of surviving multiple CIP cycles.

Measurements in the Fermentation and Storage Cellars

At standard fermentation temperatures, propagation of microorganisms is detrimental to the beer. In order to prevent this from occurring, hygienic plant design and use of materials resistant to CIP solutions are important criteria, as they are for in-line sensors.

Measurements in CIP Systems

The economic use of fresh water, as well as the multiple use of cleaning solutions, present a further basis for achieving overall cost reduction in line with the strive for greater efficiency of the brewing process. Here also, in-line systems are of help in monitoring and optimizing the relative sub-processes.

Measurements in Wastewater Treatment Facilities

Fouling of sensors in wastewater leads to uncertainty about the measurement results and can even result in measurement system failure. METTLER TOLEDO provides efficient and practical solutions in the wastewater treatment areas as well.
