CEMS and Ambient Air Analyzers
and Sampling Components

ESC Spectrum provides reliable and robust analyzers and sampling components for CEMS, stack testing, and ambient air applications. In January 2022, ESC Spectrum acquired Control Analytics. The company’s 30+ years of process monitoring application experience combined with ESC Spectrum’s air emissions monitoring and compliance expertise are an ideal combination for meeting the unique requirements of the refinery and petrochemical industries. 

Monitoring applications for analytical and regulatory requirements require high accuracy, sensitivity, and reliability levels. They must be both reliable and cost-effective. Not all analyzers are suitable for all applications. ESC Spectrum evaluates your analytical, regulatory, and budgetary requirements and gives you the best options to meet your needs.

We help facilities with their CEMS, stack testing & ambient air analyzer and sampling component needs.
