Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000, but now only requiring a single-flange installation. An in-situ measurement with a probe removes the requirement for sample extraction and conditioning and can be used in a variety of aggressive process conditions.
Built upon Yokogawa’s second generation of TDLS analyzers, the platform still retains its improved reliability, ease of installation, and reduced maintenance requirements, but now does so with a lower total installed cost for O2, CO/CH4 , and NH3 measurements.

Yokogawa’s TDLS8100 probe style analyzer operates on the principle of Tunable Diode Laser Spectroscopy (TDLS) and uses near-infrared (NIR) light to make process gas measurements. The TDLS8100 is an ideal solution for both oxygen and carbon monoxide measurements in process furnaces that have aggressive and corrosive components. The analyzer sensor is not in direct contact with the process and provides < 5-second response all while reducing time and costs associated with regular maintenance. The single flange entry allows direct replacement of conventional oxygen analyzers.
In maintaining and managing industrial plants, monitoring waste water pH/ORP is both a legal obligation and an unavoidable necessity for protecting the environment. Monitoring without an attentive eye can lead to severe consequences.
Package boilers require less fuel and electric power to operate and are widely used in the pharmaceutical, food, ceramic, and other industries. A package boiler operates more efficiently if the oxygen concentration in the flue gas is reduced.
