The Laser 3 Plus Ammonia is optimized for ammonia slip DeNOx applications

A compact, high-performance Tunable Diode Laser (TDL) analyzer, specifically optimized for ammonia slip measurement, the Laser 3 Plus Ammonia offers unparalleled installation flexibility plus cost and performance benefits.

A fast-response measurement for ammonia slip

The SERVOTOUGH Laser 3 Plus Ammonia is a revolution in TDL Absorption Spectroscopy analysis: a highly compact gas monitor for 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 Ammonia provides the most stable, repeatable results with minimal installation and maintenance costs.

A revolutionary approach to TDL gas analysis

By combining the latest advances in hardware with leading-edge software processing, the SERVOTOUGH Laser 3 Plus is a revolutionary step forward for TDL gas analysis. Servomex has approached TDL analysis afresh, creating an analyzer a fraction of the size without compromising performance. The result is TDL analysis that is easier and faster to install – saving valuable space while enabling much greater installation flexibility.

Low maintenance, low cost-of-ownership

The next-generation ethos of the Laser 3 Plus works hard to reduce costs at all stages. In addition to the immediate advantages of TDL technology – a non-depleting measurement which requires no sample conditioning system – the Laser 3 Plus compact design greatly reduces installation time, with small, light intuitive alignment for easy installation and maintenance. Full ethernet communications for commissioning, diagnostics and trouble shooting.

High performance monitoring

The hardware advances of the Laser 3 Plus are matched by advanced Wave Length Signal Modulated Spectroscopy processing software which eliminates drift over extended operational periods by automatically tracking on a sealed reference cuvette absorption line – Line Lock Technology. This robust tracking mechanism ensures a highly reliable and accurate operation over long periods, with calibration frequencies extended beyond twelve months for many applications. The result is a sturdy, general purpose and hazardous area optimized design which ensures Laser 3 Plus can handle the most challenging of locations; including particulate-rich environments.
