Optical detector LaserGas™ II SP

gasTDLtunable laser absorption spectroscopy (TLAS)

Fast response time Wide variety of gases and applications Well proven and robust design LaserGas™ II Single Path is a non-contact optical measurement method also known as in-situ. The analyzer is suitable for variety of gases and process conditions, including dual gas measurements. Laser Gas™ II SP has also a wide range of Ex-certifications, including IECEx, ATEX, CSA. The instrument does not require any consumables 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. Once power, data lines and purge are connected, the instrument is ready to use and measurements are performed in real-time.
