NEO Monitors LaserGas™ is using Tuneable Laser Absorption Spectroscopy (TLAS) i.e a non-contact optical measurement method employing solid-state laser sources. The sensor remains unaffected by contaminants corrosives and does not require regular maintenance. The absence of extractive conditioning systems further improves availability of the measurements and eliminates errors related to sample handling. The monitor is mounted directly onto flanges, which include purge gas connections and a tilting mechanism for easy alignment. Continuous purge flow prevents dust and other contamination from settling on the optical windows. Once power and data lines are connected, measurements are performed in real-time.

LaserGas™ II SP is designed for in-situ measurement in stacks, ducts, or reactors with typical path lengths in the range 0.5 to 20 meters. By-pass and extractive configurations are also possible. The monitors’ compact design comprises the transmitter unit with laser module; collimating optics, and main electronics and the receiver unit with focusing lens, photo detector and receiver electronics.
