In-situ Laser Process Gas Analyzer
In-situ laser process gas analyzer GasTDL-3100 is a high-performance laser gas analyzer based on tunable diode laser absorption spectroscopy technology (TDLAS).
With a cross-stack design, GasTDL-3100 can be used for industrial process gas control; The response time is fast, which is generally calculated in seconds in in-situ measurement. It can avoid the time delay caused by sampling measurement. The gas component concentration can be reflected online and in real time.
