LaserGas II SP Compact

Derived from the standard Single Path instrument. The Compact monitor is optimized for short distance measurement in the range 10 to 100 centimeters. It is a non-contact optical measurement method also known as in-situ.

LaserGas™ II SP Compact offers a wide variety of gases, measurement and temperature ranges and dual gas measurements. LaserGas™ 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.
It also has smaller physical dimensions compared to the LaserGas™ II SP.
