Why You Should Upgrade Your Analyzer Sooner Rather Than Later

If your analyzer is obsolete, you are risking your CEMS not having the capability to measure emissions properly to comply with regulations. This can be caused by inaccurate data, limited monitoring capabilities, maintenance challenges, or data that is incompatible with modern DAS technology and reporting requirements. With an outdated analyzer, these issues are more difficult to mitigate due to discontinued support and maintenance.

Here are a few benefits of upgrading to a newer version:

Compliance Assurance: Investing in a more up-to-date analyzer can provide you with more accurate emissions requirements, increasing ease of meeting regulatory requirements.
Enhanced Monitoring Capabilities: Updated analyzers come with more advanced features such as real-time monitoring, improved sensitivity, or a more wide range of measurable pollutants.
Operational Efficiency: Modern analyzers also require less maintenance, which can reduce downtime and added costs for your facilities.
Up-To-Date Digital Solutions: The newer your analyzer, the more compatible it may be with current data acquisition and reporting software.
