In-situ Cross-Duct TDLAS Analyzer

LAS 300 XD

TDL monitor for in-situ non-invasive measurement of NH3 & H2O, HCl & H2O, HF as well as low or high concentrations of CO and O2 in process or CEMS applications

The Tunable Diode Laser Spectroscopy (TDLS) is the perfect technology to use when you are looking for a selective measurement and a fast response time on some gas components as NH3, HCL, HF or even O2 when conditions are too rough for standard O2 Zirconia In-Situ analysers.

Tunable Diode Laser Absorption Spectrometry is the future of raw gas measurement
