Online Continuous Emission Monitoring System
NPL Certified Online Continuous Emission Monitoring System (OCEMS)
A facility to measure flow, dust, concentration of air pollutants (such as SO2, NOx, CO etc), and other parameters according to requirements. Required parameters depend on the type of stationary source.
OCEMS Package Components
OCEMS can be configured as a package integrating multiple monitoring components as per site requirements.

Frequently Asked Questions
An Online Continuous Emission Monitoring System (OCEMS) is a system used to continuously monitor and measure emissions from industrial stacks, including gas concentrations, particulate matter, and other parameters, as required by environmental regulations.
CEMS (Continuous Emission Monitoring System) refers to the overall system for continuous emission measurement, while OCEMS typically refers to an online implementation of CEMS that integrates analyzers, monitoring devices, and data transmission for regulatory reporting.
An OCEMS package can be configured to include a stack gas analyzer, suspended particulate matter (SPM) monitoring, PTZ camera for visual monitoring, and IoT-based data integration, depending on site and regulatory requirements.
The ENDA-5000 series stack gas analyzer is used within an OCEMS to continuously measure gas components such as NOx, SO₂, CO, CO₂, and O₂ as part of stack emission monitoring.
The ENDA-5000 series is used for measurement of NOx, SO₂, CO, CO₂, and O₂ in stack gas analysis applications.
SPM (Suspended Particulate Matter) monitoring is used in OCEMS to measure particulate emissions from industrial stacks as part of continuous emission monitoring requirements.
A PTZ (Pan-Tilt-Zoom) camera can be integrated into an OCEMS package to enable visual observation of the stack area as part of emission monitoring and site supervision.
IoT integration in an OCEMS enables connectivity, data transmission, and integration with control systems for centralized monitoring and reporting.
ENDA-5000 series stack gas analyzers are used in OCEMS applications where continuous measurement of regulated gas components is required, subject to applicable certification and compliance requirements.
Yes, OCEMS can be configured based on site conditions, emission sources, and applicable monitoring requirements, with different combinations of analyzers and monitoring components.
Selection of an OCEMS configuration depends on emission parameters, monitoring requirements, and site conditions. A technical assessment helps determine the appropriate system components.
