In-situ Laser Gas Analyzers

Classification：

iLAS Series

Product Description:

The iLAS series in-situ laser gas analyzer adopts the principle of Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure the concentration of specific gases in the process gas composition, including NH3, HCL, HF, H2S, CH4, O2, CO, CO2, etc. CO2, etc. The gas analyzer is characterized by high sensitivity, fast response time, no background gas interference, non-contact optical measurement, etc. It can be used in many industrial fields for gas emission monitoring, process control and other scenarios, providing a reliable guarantee for real-time and accurate reflection of gas concentration changes.
