LaserGas II MP

LaserGas™ II Multi Pass combines extractive measurement with a compact analyzer design. The laser beam is coupled into a measurement cell, where it is reflected multiple times between two spherical mirrors in order to enhance the analyzer sensitivity.

The monitor is a turn-key instrument. No other operations than connecting power, sample gas tubes and optional purge are required during installation. LaserGas™ MP provides a reliable and easy to use solution for a wide variety of applications.
