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.

A Better Way to Measure Dissolved Oxygen in Power Plant Pure Water Systems

measuring dissolved oxygen
In power plants, approximately half of unscheduled shutdowns can be traced to water cycle chemistry issues which involve costly repairs and lost operating revenue that can never be recovered. One of the most important parameters to measure to improve power plant water system efficiency is dissolved oxygen, DO. DO causes corrosion of components that contain iron and copper. Transport and deposits of these particles can also accelerate corrosion and damage critical plant equipment.

DO is measured at several locations in a water system. Traditionally, DO is measured with polarographic sensors, which use a gas permeable membrane to separate the sample from the electrochemical cell inside. Depending on the operating environment, polarographic sensors can require monthly electrolyte and membrane replacement.  After service, the sensor cannot produce meaningful readings for several hours because of required polarization. They are also sensitive to sample flow rate and experience interference from dissolved hydrogen.

Unlike traditional DO sensors, the Mettler Toledo Thornton online pure water optical DO sensor does not require polarization. It uses optical technology to provide fast and accurate analysis. Its measurement response is six times faster than polarographic sensors. The optical DO sensor also does not use electrolyte or a membrane, so it's not sensitive to flow or susceptible to damage from particles and dissolved hydrogen interference. There is no interior body to replace, and service is required only once a year to quickly and easily replace the one-piece Optocap sensing element. This provides plants with lower operating costs and reduced downtime. 

The Mettler Toledo Thornton pure water optical DO sensor provides a fast, accurate and low-maintenance method of measuring dissolved oxygen concentration in power plant pure water systems.

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.
