What's New?

 Yokogawa Data Acquisition in Temperature Uniformity Survey (TUS)

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.
