Neomonitors LaserGas™ II MP is using Tunable Diode Laser Absorption Spectroscopy (TDLAS). This non-contact optical measurement method employs solid-state laser sources. Therefore, the sensor remains unaffected by contaminants and corrosives and does not require regular maintenance. The laser beam is coupled into a Herriott cell, where it is reflected multiple times between two spherical mirrors in order to enhance the analyzer sensitivity.
