The laser diode gas analyzer : LDS 6

Product Descriptions
The in-situ gas analyzer LDS 6 is characterized by a high availability and unique analytical selectivity and is optimally suitable for numerous applications. One or two signals from up to three measuring points are processed simultaneously by the central analyzer unit. The sensors are designed for operation under harsh environmental conditions and contain a minimum of electrical components.

Wide range of applications
Besides emission monitoring there is a set of industrial applications where laser diode is already established as a standard tool for process optimization. Among the most important applications in the process industries one will find, today:
• Power generation / combustion industry
Surveillance and optimization of DeNOx plants by measuring the ammonia slip behind SCR and SNCR DeNOx installations
• Thermal waste treatment:
Primary combustion control by fast measurements of the oxygen concentration and the gas temperature in furnaces and boilers.
Surveillance and optimization of flue gas cleaning systems by measuring the waste gas concentrations before and after gas cleaning steps.
• Internal combustion engines:
Measuring the ammonia slip behind DeNOx catalysts in the waste gas system of engine test beds
• Explosion safety:
Immediate and for the intrinsically safe (Ex i) concentration measurement in combustible gases like CO and CH4 as well as for the surveillance of the oxygen level in process streams, tanks or silos.
• Corrosion protection:
Fast and non-intrusive surveillance of moisture in corrosive gas mixtures.

Benefits at a glance
• Little installation effort
• Minimum maintenance requirements
• Extremely rugged design
• High long-term stability through built-in, maintenance-free reference gas cell, field calibration is unnecessary
