The Laser 3 Plus Process Tunable Diode Laser (TDL) analyzer provides all the benefits of Servomex’s TDL Absorption Spectroscopy technology in a small, light unit, offering unparalleled installation flexibility plus cost and performance benefits. It is optimized for the fast, accurate and responsive measurement of process oxygen (O2) in hot or hazardous conditions.
The SERVOTOUGH Laser 3 Plus Process is a highly compact gas monitor for in-situ cross stack applications, delivering exceptional performance benefits in a revolutionary compact design. Its pioneering design occupies a footprint up to one-tenth the size of competitor products, providing instant benefits for installation and flexibility.
Utilizing the latest Wavelength Modulated Spectroscopy (WMS) measurement techniques with unique Servomex signal processing, it provides the most stable, repeatable results for the measurement of O2, with minimal installation and maintenance costs.
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.
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.
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.
