This TDL spectrometer performs accurate O2 measurements

| By Gerald Ondrey

The TDLS8220 extractive tunable diode laser spectrometer (photo) is a new generation OpreX analyzer. The TDLS8220 laser module and detector module are now encompassed in one board set, but still retain a reference cell for improved reliability of absorption peak detection. In addition, the automatic gain function optimizes detection sensitivity during dynamic process events. Due to the non-contact measurement, sample-handling system upsets or failures will not damage the analyzer sensor. The unique flow-cell design features a tube-in-shell construction that allows tight temperature control of extractive samples at the desired setpoint. The analyzer does not require consumables, and solid-state technology eliminates the need for routine calibration. — Yokogawa Corp. of America, Newnan, Ga.
