Laser Gas Analyzer

Classification：

uLAS Series

Product Description:

The uLAS laser trace gas analyzer is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS } technology, which scans and analyzes gas absorption spectra at specific wavelengths and combines advanced technologies such as digital lock-in amplifiers and long-range gas chambers to achieve gas concentration measurements. uLAS laser trace gas analyzers can achieve high-resolution, high-precision, stable and reliable measurements of trace gases. The uL AS laser trace gas analyzer can meet the requirements of process analysis and environmental testing applications.
