  • 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.

  • 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.

  • The TDLS8000 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.
