LaserGas™ III SP is the third generation in-situ analyzer, designed for safety applications with a special focus on SIL-applications and Ex-d. A compact sized instrument which is easy to install. The instrument is a placed in a sealed housing which eliminates the need for instrument purging.The instrument does not require regular maintenance.

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.
