TES CEMS
Engineered to monitor emissions with precision
Continuous Emission Monitoring Systems (CEMS) are required for facilities that emit pollutants from combustion or industrial processes. CEMS offers precise, real-time data to aid in environmental control and air quality regulation adherence. Energy, waste-to-energy, chemicals and manufacturing are some of the industries that utilise CEMS.
CEMS typically monitor gases such as CO, CO₂, SO₂, NOₓ, O₂, NH₃, HCl, H₂S, VOCs, CH₄, N₂O, TRS, H₂O, mercury, particulate dust and gas flow/velocity. Properly installed and maintained, they provide critical data for safer operation and regulatory reporting.
Here’s How We Can Help You Monitor Emissions
TES engineers fully integrated CEMS solutions, designed specifically for your process and site conditions. Using advanced technology, like FTIR and optical scintillation, we measure pollutants even in extreme environments. From equipment selection to final installation, we offer practical and innovative turnkey systems.
In-situ Systems
Installed directly in the stack, in-situ systems deliver immediate measurements without sample conditioning, ideal for cleaner applications.
INSITU GAS CEMS
Installed directly into the stack, in-situ CEMS eliminate the need for sample conditioning, offering low-maintenance, high-integrity monitoring. Designed to measure one or a few gases, these systems deliver fast, accurate results, even in harsh environments.
INSITU DUST/OPACITY ANALYSERS
TES supplies EPA- and TUV-compliant dust and opacity monitors, including laser and triboelectric models. These emission monitors offer reliable, cost-effective options for environmental and process dust monitoring.
INSITU FLOW/VELOCITY SENSORS
TES offers Ultrasonic and Optical Flow Sensors for non-contact, drift-free flow monitoring. Suited for stacks and ducts, they’re rugged, low-maintenance and meet US EPA 40CFR 60/75 standards for regulatory reporting.
Extractive Systems
Gas is continuously drawn from the stack down heated umbilical lines and conditioned (filtered and cooled) before being analysed by sensitive analysers, ensuring accurate results in tough environments.
Our systems include:
- Gas analysers specifically chosen for the application
- Dust/opacity monitors
- Flow/velocity sensors
- Sample probes, calibration tools and enclosures
- Factory-tested components for quality assurance
DIRECT EXTRACTIVE AND DILUTION EXTRACTIVE CONTINUOUS GAS ANALYSER SYSTEMS
Designed for tough emissions and process monitoring, these systems handle corrosive gases like H₂S and TRS with ease. Customised for your site, they feature high-temp options, data logging and multiple gas measurement capabilities.
Featured Equipment
GASMET CMM CONTINUOUS MERCURY MONITORING SYSTEM
Gasmet CEMS II e Gas analyser can measure up to 50 different gas components simultaneously, including H₂O, CO₂, CO, NO, NO₂, N₂O, SO₂, HCl, HF, NH₃, CH₄, Speciated VOC's and Total Organic Carbon (TOC). Ideal for measuring trace concentrations of pollutants in wet, corrosive gas streams, its typical application is monitoring of waste incinerator or large combustion plants.

Selecting the right technology for your specific stack parameters is essential for accurate, reliable monitoring. TES offers a range of proven technologies and will tailor your CEMS design to suit your site requirements, maximising uptime and minimising maintenance.
CEMS uses equipment like analysers, probes and software to sample and analyse emissions continuously in real time, typically from industrial stacks. They are typically a legal requirement and provide true continuous information for emission control, environmental protection and optimum operating conditions.
CEMS typically monitors controlled pollutants such as CO, CO₂, NOₓ, SO₂, H₂S, TRS, VOCs, and particulates. Monitoring meets environmental needs, protects public health and improves process performance by offering real-time emission monitoring system reports.
