FAST-RESPONSE LASER O 2 MEASUREMENTS

THE ACCURATE MEASUREMENT OF PROCESS OXYGEN ( O 2 ) IS KEY TO MANY HP PROCESSES . SERVOMEX OFFERS A STABLE , RAPID , LASER-BASED SOLUTION .
The SERVOTOUGH Laser 3 Plus Process is a compact Tunable Diode Laser ( TDL ) analyzer specifically optimized for fastresponse measurement of process O 2 .
Designed for in-situ , cross-stack measurements , it uses the latest Wavelength Modulated Spectroscopy measurement techniques and unique Servomex signal processing to monitor O 2 in multiple gas backgrounds .
Easy to install , configure and calibrate by just one person , the Laser 3 Plus uses a mounting assembly for multi-directional adjustment , ensuring precision alignment from the outset . When combined with the quick-release mechanism , it is easy to achieve fast , accurate reinstallation after maintenance , without the need for realignment .
The Laser 3 Plus uses line lock cuvette technology to ensure gas measurements that are reliable to SIL 2 levels , a clear advantage to safety systems .
Thanks to a cuvette filled with the target gas , the secondary detector always has a known target gas to sense . This enables the main detector to remain “ locked ” in position , giving an accurate measurement of the gas , even if that measurement is zero .
The line lock system requires no maintenance and has built-in diagnostics that monitor the concentration within the cuvette .
The stability and reliability of this system provides measurement confidence in applications where incorrect measurements may affect safety or lead to heavy fines for non-compliance .
