Tunable Diode Laser Spectrometers

Tunable Diode Laser Spectrometers (TDLS) are laser-based gas analyzer with fast-update optical analysis. The TDLS line offers measurements for process gas, flue gas, impurity analysis, custody transfer, safety, with in-situ and extractive methods supported. In the chemical, power and refining industries, Yokogawa TDLS technology is acknowledged in a 2012 EPRI research study and the API 556 standard as the technology required for safe and environmentally responsible combustion applications.

  • product_TDLS220

    The TDLS220 analyzer is specifically designed for accurate, reliable and low maintenance measurement of volume percent (vol%) oxygen in process gas streams. It is capable of measuring oxygen in a variety of process applications with gas temperatures up to 120 °C and pressures up to 100 psi under difficult conditions such as corrosive and aggressive service.

  • Extractive Impurities Gas Analyzer TDLS500 (DISCONTINUED)

    With the TDLS500 (ICOS) analyzer, rapid and continuous measurements are possible for the first time in a process hardened analyzer. Traditionally trace level analysis in process conditions has required the use of process gas chromatographs. The major drawback of this approach has been the analysis time required (typically minutes), and the fact that a continuous measurement is not possible.

  • TDLS80001

    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.
