Online Continuous Emission Monitoring System (OCEMS)
An Online Continuous Emission Monitoring System (OCEMS) is an advanced environmental monitoring solution designed to measure and record emissions from industrial stacks in real time. It continuously monitors pollutants such as Particulate Matter (PM), Sulphur Dioxide (SO₂), Nitrogen Oxides (NOx), Carbon Monoxide (CO), and Oxygen (O₂) to ensure that emissions remain within permissible limits.
The system automatically collects, analyzes, and transmits emission data to regulatory authorities such as the Central Pollution Control Board (CPCB) and respective State Pollution Control Boards (SPCBs) as mandated under environmental regulations. Greenshield Enviro provides reliable OCEMS solutions that help industries maintain compliance, improve transparency, and manage emissions efficiently.

Real-Time Stack Emission Monitoring for Regulatory Compliance
OCEMS is designed to continuously measure and record emissions from industrial stacks in real time. It provides industries with a dependable way to monitor pollutants, maintain traceable records, and ensure compliance with environmental norms.
Industries operating boilers, furnaces, incinerators, or thermal processes must continuously monitor emissions to comply with environmental regulations. OCEMS supports automatic monitoring, emission tracking, and direct integration with regulatory servers for better transparency.
With real-time data collection, automated analysis, and reporting capability, OCEMS helps industries detect emission exceedances immediately, improve operational efficiency, and maintain sustainable and responsible operations.
Compliance assured. Emissions tracked. Operations made transparent.
Our OCEMS solutions help industries monitor stack emissions in real time, automatically transmit data to CPCB/SPCB servers, and reduce the risk of violations through accurate and continuous environmental tracking.
