Open-path Laser Gas Analyzer

Classification：

oLAS Series

Product Description:

The oLAS series open circuit laser gas analyzers are designed for open space ambient air quality monitoring, with a minimum detection lower limit up to ppb level within the optical range of hundreds of meters, especially suitable for monitoring ambient air pollutants (unorganized emissions) in industrial parks or production plants, such as HCL, HF, NH3, H2S and other gases. Compared with the extraction system, the open laser gas analyzer realizes the real sense of ambient air monitoring at the field boundary.
