CEMS Monitoring and Calibration
Keep your operations running smoothly with Element's rapid-response Continuous Emissions Monitoring Systems (CEMS) Monitoring, calibration and emergency back-up services. For full compliance including BS EN 14181 calibration, testing or the installation of temporary systems, our MCERTS-accredited solutions ensure continuous environmental compliance without operational disruption. Local expertise, backed by the UK and Ireland’s largest fleet of portable monitoring systems.
What are CEMS Emissions Monitoring services at Element?
Temporary CEMS provides backup emissions monitoring when your permanent systems are unavailable. Element deploys MCERTS-accredited portable monitoring systems to measure stack emissions, ensuring continuous compliance with environmental permits during both planned maintenance and unexpected breakdowns. Our systems integrate seamlessly with your existing operations.
What CEMS Emissions Monitoring services does Element offer our clients?
What we test
What we test
Element’s emissions teams install CEMS to monitor the full spectrum of emissions parameters including NOx, NO, NO2, N2O, CO, CO2, O2, TVOCs, SO2, HCl, NH3, and H2O (water vapor). Element’s systems are calibrated to your specific stack gas composition and temperatures, ensuring accurate measurements across all required parameters.
Element’s comprehensive services also cover your complete CEMS infrastructure, including monitoring systems, BS EN 14181 calibration, and emissions control equipment. Element conduct thorough linearity checks at 2x Daily ELV or Short Term ELV using ISO/IEC 17025 certified calibration gas with <2% uncertainty, ensuring accurate system validation.

Frequently asked questions
What is included in a linearity check?
Linearity checks assess CEMS performance at zero, 20%, 40%, 60%, 80% of range, and final zero. Includes T90 response time determination and additional required checks.
How often are QAL2 and AST tests required?
QAL2 requires minimum 15 parallel measurements over 3 days. ASTs are conducted annually with minimum 5 parallel measurements over 1 day.
What is QAL3 and how often should it be conducted?
QAL3 is an ongoing quality assurance and control process for CEMS, typically conducted by the operator on a routine basis (weekly, fortnightly or monthly) to demonstrate systems are functioning normally and remain under control.
