Laser-focused on gas analysis: the Laser 3 Plus range

Servomex’s SERVOTOUGH Laser 3 Plus range delivers fast, accurate gas analysis in a light, compact design.

Using our own Tunable Diode Laser (TDL) technology, the latest Wavelength Modulated Spectroscopy (WMS) measurement techniques, and unique Servomex signal processing, it provides the most stable, repeatable results with minimal installation and maintenance costs.

The Laser 3 Plus Combustion model measures oxygen (O₂), carbon monoxide (CO), or CO and methane (CH₄) in in-situ cross-stack applications, delivering exceptional performance benefits.

The Laser 3 Plus Process version provides the most stable, repeatable results for the measurement of O₂ in process temperatures up to 500°C.

And the Laser 3 Plus Environmental reliably measures ammonia (NH₃) for monitoring ammonia slip during DeNOx processes. It is also EPA PS18 compliant for CEMS monitoring of NH₃ as a precursor to harmful particulates.

The analyzer’s pioneering compact design occupies a footprint one-tenth the size of many competitor products, providing instant benefits for installation and flexibility.
