NEO Monitors LaserGas™ Q NO 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.
