Open Path Gas Analyzers

The NEO Monitors LaserGas Analyzer is capable of measuring many near-infrared absorbing gases in process environments. The LaserGas Series of analyzers are capable of measuring from the simplest of applications with difficult high temperature and pressure conditions to environmental applications with agressive, corrosive and high particulate. The LaserGas analyzer is the #1 most installed TDL process analyzer in the world.


TDL absorption spectroscopy is well suited for long distance monitoring of gases in ambient air, so called Open Path measurement. The instruments detect the average gas concentration along the optical line of sight between transmitter and receiver. Distances of up to 1000 m can be covered.
