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

InTap™ 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.

Inline Dissolved Oxygen Sensor Designed for Breweries

Oxygen in beer bottles or cans is bad. It affects the flavor and shortens shelf life, so breweries do their best to prevent oxygen getting into beer  at the filling line.  The Mettler Toledo Process Analytics InPro6970i is an inline dissolved oxygen sensor designed specifically for the needs of the brewery industry. It can measure oxygen in beer at levels of only a few parts per billion.

The sensor is inserted in the pipe at the start of the filling line, and provides real-time measurements on the oxygen content of the beer.  If the oxygen level is too high, the flow of beer is stopped to prevent the out of specification product continuing down the line.

Unlike most dissolved oxygen sensors available, the InPro6970i uses a clever optical technique for measuring oxygen. At the tip of the sensor there's a layer of molecules that absorb and emit light. These molecules are sensitive to oxygen which alters how the molecules behave. The greater the quantity of oxygen, the greater the changes in their behavior. The sensor very accurately measures these changes and sends the signal to the transmitter.  This technique is extremely fast and accurate at measuring changes in beer oxygen level, which is why it is favored by breweries. But that is not the only requirement breweries demand.  Sensors must be rugged, easy to use, and simple to maintain.The InPro6970i scores highly in all these areas. The sensor's stainless steel body is extremely robust, the unit is easily and quickly installed, and the only maintenance required is the periodic exchange of the oxygen sensitive element, the OptoCap. Intelligent Sensor Management, or ISM, is a feature of the InPro6970i that offers significant benefits to breweries. The sensor can be calibrated in a convenient location such as a lab. Upon connection to the transmitter, the system is ready to measure in only a few seconds, so measurement point down time is very short. The dynamic lifetime indicator uses sophisticated algorithms to calculate the remaining life of the sensor, breweries therefore have confidence that the sensor won't fail unexpectedly.

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.

Optical Sensor for Dissolved Oxygen Monitoring in Breweries



Dissolved oxygen measurements are an essential part of the brewing process. Keeping oxygen out of beer is a key production goal of brewers on any scale, since oxygen noticeably diminishes the taste of beer.

The measurement levels for oxygen are very low, so a sensor with high accuracy and response is needed. Hygienic construction and the ability to accommodate CIP operations is also a plus. Any features that reduce maintenance time budget enhance the value of the instrument.

The video, provided by Mettler Toledo, provides useful insight into how their optical DO sensor can benefit a brewing operation.

More detail, as well as application assistance, is available from product specialists. Combining your process knowledge and experience with their product application expertise will deliver effective solutions.
