Process Analyzers

Improving the operation, reliability, and credibility of online process analyzers

Process analyzers are on-line tools for industrial process analytics. They are used to determine the chemical composition or physical properties of substances involved in industrial processes. They enable process optimization, asset protection, and compliance with environmental regulations.

With one of the most comprehensive families of sensors and on-line analyzers for pH, conductivity, dissolved oxygen, combustion oxygen, humidity, liquid and gas density and process gas chromatography, Yokogawa is recognized as a world leader in the field of analytical equipment. Accurate, repeatable measurement is the key to obtaining optimal results in your process, and Yokogawa's diagnostic-based analytical instrumentation offers the flexibility to meet a range of individual requirements. Whether for liquid or gas applications, our analyzers can resolve even the most demanding situations. Yokogawa's leadership in process analytics helps to protect the environment by reducing energy consumption and CO2 emissions. 

  • Real-time gas analysis enhances efficiency, safety, throughput, product quality, and ensures environmental compliance.

  • Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control.

  • Analytical solutions for gas and liquid measurements to support product refinement, process efficiency, and safety. 

  • Our analytical services include installation and construction, startup and commissioning, and training services. 


Specialized online analyzers, standardized sampling systems and other advancements are helping process plants move more measurements from offline in labs to online in-situ. The move from remote analyzer shelters to a pipe-centric approach where analyzers are installed at or near the sample tap will further cut costs, reduce maintenance and improve process control.

Motor fuels are complex products. Various diesel fuel and gasoline grades are prepared from a large range of individual blending components whose individual properties may be extremely variable over time. Each day, refiners must determine the blend recipe based on the properties, value and availability of those components, as well as the target specifications for the product. Once that is done, the operational challenge is to verify that the blended product delivered to the pipeline actually meets those contractually defined specifications.

    Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning. The non-contacting sensor allows for a variety of process types including corrosive, abrasive and condensing. The first generation platform has been proven in many others for the measurements of O2, CO, CH4, NH3, H2O and many more NIR absorbing gases. This second generation platform has improved reliability and ease of installation and maintenance while still meeting or exceeding designed application demands.
