General description

Overview
LDS 6 is a diode laser gas analyzer with a measuring principle based on the specific light
absorption of different gas components. LDS 6 is suitable for fast and non-contact measurement
of gas concentrations or temperatures in process or flue gases. One or two signals from up to
three measuring points are processed simultaneously by one central analyzer unit. The in-situ
cross-duct optics housing at each measuring point can be separated up to 700 m from the
central unit by using fiber-optic cables. The optics housing are designed for operation under
harsh environmental conditions and contain a minimum of electrical components.

Benefits
The in-situ gas analyzer LDS 6 is characterized by a high availability and unique analytical
selectivity, and by a broad scope of suitable applications. LDS 6 enables the measurement of one
or two gas components or – if desired – the gas temperature directly in the process:
• With high levels of dust load
• In hot, humid, corrosive, explosive, or toxic gases
• In applications showing strong varying gas compositions
• Under harsh environmental conditions at the measuring point
• Highly selective, i.e. mostly without cross-sensitivities
LDS 6 properties:
• Little installation effort
• Minimum maintenance requirements
