Exhaust Gas Analyzers UV-GAS-500 SO2 NO NO2 CO CO2 O2 for CEMS


An exhaust gas analyzer is a device that measures the concentration of gases in a sample of exhaust gas. Exhaust gas analyzers are used to monitor the emissions of vehicles, engines, and other industrial equipment.


Exhaust gas analyzers typically use a variety of sensors to measure the concentration of different gases in a sample of exhaust gas. The most common sensors are infrared absorption sensors, which measure the amount of infrared light that is absorbed by the gases in the sample. Other sensors that are used in exhaust gas analyzers include electrochemical sensors, chemiluminescent sensors, and mass spectrometers.


The data from the sensors is collected by the exhaust gas analyzer and displayed on a screen. The data can be used to monitor the emissions of a vehicle or engine, or to troubleshoot problems with an industrial process.


Exhaust gas analyzers are an important tool for monitoring the emissions of vehicles, engines, and other industrial equipment. They can help to ensure that these devices are operating in a safe and environmentally responsible manner.


What is the difference between a gas analyzer and an exhaust gas analyzer?


A gas analyzer is a device that measures the concentration of one or more gases in a sample. Gas analyzers are used in a variety of applications, including environmental monitoring, industrial process control, and medical diagnostics.


An exhaust gas analyzer is a type of gas analyzer that is specifically designed to measure the emissions of vehicles, engines, and other industrial equipment. Exhaust gas analyzers are used to monitor the emissions of these devices to ensure that they are operating in a safe and environmentally responsible manner.


The main difference between a gas analyzer and an exhaust gas analyzer is the type of gases that they are designed to measure. Gas analyzers can measure a wide range of gases, including carbon dioxide, methane, nitrous oxide, and oxygen. Exhaust gas analyzers are typically designed to measure a smaller number of gases, such as carbon monoxide, hydrocarbons, and nitrogen oxides.


Gas analyzers and exhaust gas analyzers are both important tools for measuring the concentration of gases in a sample. Gas analyzers are used in a variety of applications, while exhaust gas analyzers are specifically designed to monitor the emissions of vehicles, engines, and other industrial equipment.


Emissions Gas Ananalyzer UV-GAS-500 SO2 NO NO2 CO CO2 O2 is a crucial component of a Continuous Emission Monitoring System (CEMS). It typically consists of several components that can measure the concentration levels of SO2, NO and NO2 in flue gases. The CEMS also includes additional features such as gas pressure and gas temperature sensors,dust monitor alarms, data logging systems, and other necessary instruments. To ensure an accurate and consistent measurement of emissions, the analyzer can be integrated into an online system to provide continuous monitoring and real-time data acquisition.


  • Air Quality
  • Environment Protection
  • People Safety

UV-based technology is widely used for measuring SO2, NO and NO2 levels due to its cost-effectiveness and accuracy. It has a high degree of precision and can measure even lower concentrations of these gases. However, one major advantage is that it can directly measure NO2; instead, infrared gas analyzer needs to be converted NO2 into NO first before it can be measured. This conversion process can be costly and time-consuming.


An emission gas analyzer is a powerful tool for measuring and monitoring the concentration of various gases like sulfur dioxide (SO2), nitric oxide (NO), nitrogen dioxide (NO2) in the air. Moreover, it has the capability to add other gases such as carbon monoxide (CO), oxygen (O2), and carbon dioxide (CO2) into a single unit, offering greater flexibility. This makes it an ideal solution for industrial applications where the environmental impact of emissions must be closely monitored and documented. The emission gas analyzer can help detect even small changes in atmospheric gas concentrations over time, providing accurate data to inform decision-making processes. It is also capable of producing detailed reports regarding the quality of the air in a given area, which can be used to ensure compliance with environmental regulations. Ultimately, an emission gas analyzer is a vital component for ensuring that our environment stays healthy and safe.


1. High Sensitivity and Selectivity: The technology used in the analyzer provides high sensitivity and selectivity for the target gases.


2. Data Logging and Analysis: Many models have built-in data logging and analysis capabilities, enabling detailed reporting and trend analysis.


3. Compliance and Reporting: Ensures compliance with environmental regulations and provides data for regulatory reporting.


4. Robust Design: Designed for reliability in industrial environments.
