Emissions and Air Quality Testing in Transportation

Smart, Scalable Solutions for Real-Time Emissions Control and Environmental Compliance

Emissions and Air Quality Testing
Technologies in Transportation

Growing concerns about air pollution and strict regulatory mandates have made emissions and air quality testing essential for maintaining cleaner, more efficient transportation systems. These technologies are pivotal in helping transportation networks adapt to evolving standards while optimizing performance and sustainability. Across North America, B2B sectors—from fleet operators and vehicle manufacturers to inspection agencies—depend on high-precision tools to monitor pollutants, ensure compliance, and make data-driven improvements.
Through real-world testing, advanced analytics, and seamless system integration, emissions monitoring technologies now go far beyond basic diagnostics. They support proactive maintenance, environmental accountability, and smarter policy implementation across personal vehicles, heavy-duty engines, and mass transit systems.
With a strong foundation in research, product development, and technical guidance, our team empowers clients with scalable solutions built for reliability and regulatory confidence. Every system is designed to perform in dynamic, real-world conditions—ensuring cleaner air and smarter mobility outcomes across the transportation industry.

Discover Our Extensive Selection of Advanced Emissions and Air Quality Testing Technologies for Transportation

In addition to our proprietary emissions and air quality testing systems and those developed with our technology partners, Envirotest Transport is proud to provide state-of-the-art solutions from our trusted affiliates, GAO Tek Inc. and GAO RFID Inc. These valuable collaborations enable us to offer dependable, high-accuracy monitoring technologies with seamless integration and expert support—helping you maintain safe, stable, and compliant critical environments.

Portable Emissions Measurement Systems

PEMS are advanced mobile systems designed to measure vehicle emissions in real-world driving conditions. Unlike laboratory-only tests, PEMS captures data on NOx, CO2, CO, HC, and particulates under dynamic load and traffic scenarios. These systems are vital for regulatory validation, R&D, and fleet-level emissions auditing. At Envirotest Transport, we offer compact, lightweight PEMS solutions with high data fidelity and integration-ready software.

Chassis Dynamometers

Our high-performance chassis dynamometers simulate on-road conditions in controlled environments, allowing for standardized emissions and fuel economy testing across various vehicle types. Dynamometers from Envirotest Transport support light- and heavy-duty vehicles, helping OEMs, inspection stations, and researchers evaluate compliance and performance under repeatable load cycles.

Engine Exhaust Gas Analyzers

Engine exhaust gas analyzers are crucial for accurately detecting and quantifying combustion byproducts. Our analyzers offer real-time measurements of gases like CO, CO₂, O₂, NOx, and unburned hydrocarbons (HC), and they meet or exceed international standards for emissions testing. We provide both stationary and portable analyzers, suitable for field diagnostics or lab-grade testing environments.

Remote Sensing Devices

RSD technologies use infrared and ultraviolet beams to measure emissions from vehicles as they pass by monitoring sites—without requiring any contact or stoppage. Our RSD solutions enable large-scale screening of high-traffic zones, helping municipalities and agencies target enforcement, research high-emitting sources, and design cleaner transport policies. These devices are ideal for real-time roadside emissions monitoring and environmental surveillance.

Onboard Diagnostics Systems

Envirotest Transport offers OBD-II and HD-OBD compatible tools that access vehicle computer data to identify emission-related faults. These systems provide a non-invasive way to monitor compliance and detect problems before they lead to excess emissions or regulatory violations. OBD systems are essential for fleet managers and inspection stations seeking reliable, digital-first diagnostics.
