The SERVOTOUGH Laser 3 Plus Combustion is a revolution in TDL Absorption Spectroscopy analysis: a highly compact gas monitor measuring oxygen (O2), carbon monoxide (CO) and methane (CH4) in in-situ cross stack applications, which delivers exceptional performance benefits.

Our pioneering approach to design has produced an analyzer that occupies a footprint up to one-tenth the size of competitor products. This provides instant benefits in terms of installation ease and flexibility.

Combining the latest Wavelength Modulated Spectroscopy (WMS) measurement techniques with unique Servomex signal processing, the Laser 3 Plus provides the most stable, repeatable results with minimal installation and maintenance costs, offering a fast response measurement of O2, CO or a combination of CH4 and CO.
