The In-Situ TDLS gas analyzer has been designed for meeting the requirements of a large range of CEMS and Process applications.
LAS 5000XD uses Tunable Diode Laser Spectroscopy (TDLS) and comes in various models for measuring parameters such as NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, etc.
It combines robustness, fast response time (1 s) and high accuracy measurement in harsh environments (ready for Ex Zone II).
Key operator benefits of LAS 5000XD In-Situ laser gas analyzer:
- No sampling system needed
- No gas temperature influence
- Gas matrix interference free
- Calibration free measurement
