Tunable Diode Laser Absorption Spectroscopy (TDLAS) Analyser
AtLAS-700 is a rack type tunable laser gas analyser for industrial on line applications. The analyser combine the TDLAS technology and multiple reflection long optical path technology that can measure a variety of gas.
Reflected light can be customized according to the working condition demand, allowing to measure each gas from high percentage down to traces.
