Laser Gas Analyzer


Product Description:

uLAS series laser gas analyzer is a high-performance laser gas analyzer developed according to the requirements of on-site industrial online analysis and environmental protection online monitoring at home and abroad. The analyzer uses tunable semiconductor Laser Absorption spectroscopy (TDLAS) detection technology with ultra-low monitoring limits and detection limits up to ppb levels. TDLAS technology has higher spectral resolution than other gas measurement principles, and thus has excellent resistance to background gas cross interference, improving the accuracy and reliability of process gas analysis. The analyzer can be customized according to the condition of the gas (O2, CO, NH3, H2S, CO2, CH4, HCN)
