Air analyzer CLD C50™

nitrogennitric oxidegas

Overview
The AVL CLD C50™ is a lightweight, compact chemiluminescence detector for continuous nitrogen oxides (NOX) monitoring in process industry and laboratories. Suitable as a stand-alone indoor analyzer or as a 19" rack-mounted stack analyzer in emission measurement systems, it supports power plants, manufacturing sites and industrial emission control applications.

Key capabilities

• Continuous NOX measurement using chemiluminescence detection.
• Compact and portable design for easy transport and flexible deployment.
• Low supply gas requirements by using ambient air for ozone generation.
• Available as a front-panel controlled stand-alone unit or as a 19" rack version (without front panel).

Benefits

• Flexible deployment: compact, transportable instrument for on-site and laboratory use.
• Serviceability: modular construction and accessible components for fast maintenance.
• Reduced operating costs: ambient-air ozone generation minimizes additional gas needs (except calibration gases).
• Simple operation: automatic calibration and one-click data recording routines.

Operational notes
Designed for a wide range of ambient temperatures with industry-leading quench specifications to compensate H2O and CO2 interferences. Required gases: ambient air for ozone generation and a span gas (NO in N2) for calibration. Offered as a stand-alone unit with local front-panel control or as a 19" rack-mount analyzer without front panel.
