Our Continuous Emission Monitoring Systems help you comply with EPA regulations. Through continual compliance we also ensure your chambers function at peak efficiency with the help of a suite of our products. These custom-developed products cater to your plant’s requirements and deliver seamless technological controls right on your fingertips.

Why CEMS over traditional?

Comply with legislation

CEMS lets you easily comply with limits that have been imposed on the quantum of emissions. The limits range from particle to particle and adhering to the rules is necessary for smooth operations.     

Data based Improvement Opportunities

With round the clock availability of real-time data your operations can be improved by many folds. Data acquisition and reporting features let you take revised decisions which prove to be extremely rewarding. The data recorded/observed is gathered either through analog outputs connected to a recording system or sent directly to a Data Acquisition System for storage and further transmission.


Workflow of Data Acquisition Systems working with our CEMS

Automated Analysis

All the major steps in traditional analysis like sample collection, transportation, conditioning, calibration and analysis procedures including quality control are usually automated in the sampling systems and on-line analyzers.

Predictive Analytics

Disturbance or abnormality in production process or the pollution control system is recurring. CEMS analyzers are always on the line to provide timely information for taking immediate preventive and corrective steps compared to conventional methods.

Data Acquisition, Management & Reporting

Taking into account the complexity of real-time monitoring systems industries are required to submit real-time data through their respective instrument suppliers. This mechanism shall help in consolidating the data avoiding the complexity of different technologies and availability of monitored data in different data formats while involving the instrument suppliers in data transferring mechanism. The system enables two ways communication required to manage such real-time systems.

Our Sampling Technique

We apply the ideal extraction sampling technique. The process starts with the sample being drawn in a continuous manner from the gas stream through a filter to remove particulates and is then sent through a conditioning system to remove moisture and other inconsistencies. Finally, the conditioned gas is sent to the analyzers to be evaluated for numerous parameters, which are collected and compiled by a data acquisition system, for customizable reporting and full compliance with regulating bodies. Some activities we deploy onsite are:

  • Diluent Gas Monitoring

  • Pollutant Concentration Monitoring

  • Hydrocarbon Analysis

  • Opacity/Dust Density Monitoring

  • Exhaust Monitoring

  • Data Acquisition & Reporting


Use Cases


Process heaters and FCC units often require enhanced sample handling features that are an IOTahead specialty.

Gas Turbines

Our CEMS solutions are ideal for the low emissions requirements for gas turbines.

Cogeneration Facilities

Depending upon the geographic location, type of fuel burned, and plant size, any or all of the following parameters may be monitored: CO, O2, CO2, SO2, NOx, THC, NH3, and opacity.

Utilities and Municipalities

With emissions allowances being a potentially valuable commodity, accurate and reliable CEMS are a necessity.

Industrial, Commercial & Institutional Boilers

Some measurements include SO2, CO, CO2, NOx, O2, and opacity. A CEMS seems mandatory in such a case regardless of the size and geographical location of the plant.

Pulp and Paper

Pulp and paper facilities are always required to monitor SO2, O2, CO, NOx, and opacity in a variety of emissions sources, including all the power and recovery boilers.

What we prevent from releasing

Our custom-engineered systems measure multiple gases using data acquisition and handling. They are programmed and designed to perform rotatory checks automatically and even when unattended. With automatic calibration it is less costly and time-consuming to meet the environmental requirements for daily validation of the system. Some pollutants we keep an eye on are:

  • Sulfur Dioxide (SO2)

  • Nitrogen Monoxide (NO)

  • Nitrogen Dioxide (NO2)

  • Carbon Dioxide (CO2)

  • Oxygen (O2)

  • Carbon Monoxide (CO)

  • Total Hydrocarbon (THC)

  • Hydrogen Sulfide (H2S)

  • Opacity
