Ready to ShipA portable emission analyzer comes in different types to suit multiple industrial requirements and setups.
Gas analyzers
These are primarily used to measure the concentration of pollutants in the emitted gases, such as carbon monoxide, nitrogen oxides, sulfur dioxide, and hydrocarbons in the atmosphere. They work by drawing a sample of air and using chemical sensors to quantify gas levels. For example, the electrochemical cell can identify and measure carbon monoxide concentration in less than a minute.
Particulate analyzers
These are designed to measure particulate emissions, especially in industries where dust and particle matter are a concern. They can seamlessly analyze the PM10, PM2.5, or any other specified particulate matter. The basic operating principle of particulate analyzers involves drawing air through a filter or impaction groove, depending on the design.
Opacity monitors
These work by measuring the amount of visible light that is blocked or obscured by the emission plume. In other words, they can detect how much smoke or particulate matter passes in the atmosphere. Opacity is a crucial parameter for industries such as power plants that need to control visible emissions. High opacity levels indicate that the air is not clear and that the emission contains dangerous or unhealthy substances.
Multi-gas analyzers
They can simultaneously measure and provide readings for multiple gas concentrations. This MultiGas usage saves time and provides a more comprehensive emissions profile in one go.
Dilution extractive analyzers
These are fitted with sample extraction and dilution mechanisms to ensure that gas samples are within measurable limits and do not corrode or damage the analyzer hardware. They analyze very high concentrations of gases.
Compliance Monitoring
Industries need to comply with environmental regulations and safety standards. This portable emission tester helps in checking and generating periodic emission reports.
Industrial Safety
Excess emission of toxic gases can endanger the health and safety of workers who work in confined or open spaces. Using this emission analyzer, such risks can be preemptively checked and avoided.
Research and Development
The emission analyzers, mainly the multi-gas ones, are widely used in R&D settings, especially in the automotive and aerospace industries, to develop low-emission technologies.
Maintenance and Troubleshooting
Emission issues cause waste and may end up being very dangerous. Therefore, periodic checking and troubleshooting are a must. The portable emission analyzer helps in timely maintenance and fixes potential problems.
Field Testing
Emission levels from installed machines can be analyzed with portable emission analyzers in industrial fields to ensure what was expected during installation was achieved or to get what was needed without going back to the lab.
Measurement Range
Most portable emissions analyzers can measure gas concentration in the range of parts per million (PPM) to percentage volume for various gases. For PM, it may be up to 1500 µg/m³.
Battery Life
They are usually designed with rechargeable batteries that last for a typical work shift—5 to 8 hours—and can also be fast-charging.
IP and NEMA Rating
The portable emission analyzer may typically be rated IP65 or equivalent to NEMA Type 4 to ensure protection from dust and water jets. This increases durability.
Data Storage Capacity
This can be between 1000 and 2000 measurement records under normal circumstances. Some advanced types may support external memory cards for increased capacity.
Prepare Calibration Gases
Make the required calibration gases. Usually, they are a mixture of known concentrations of the target gases in the air.
Install the Sampling Probe
Attach the sampling probe to the emission source to collect gas samples for analysis.
Connect Tubing
Connect one end of the tubing to the probe and the other to the analyzer to transport the gas samples.
Power On the Analyzer
Once all connections are done, power on the analyzer and check that the battery level is OK.
Calibrate the Device
Calibrate it by following the manufacturer's instructions. This usually involves at least one adjustment using a known gas concentration.
Select the Parameters
After calibration, emission testers are used by choosing the desired measurement parameters such as gas type, particulate matter, etc.
Take a Reading
Once all emission levels are set up, the reading is taken by sampling the emission from the source. The results are analyzed in real time and displayed on the screen.
Data Logging
During the test, all observed values can be logged into internal memory for later reference.
Frequent Probe and Filter Check
The sampling probe and filter are the primary components that might get clogged with the particulate matter inside the emission. The analyzer can give inaccurate values due to this probe clogging or filter blocking. Therefore, often check and clean or replace them as needed.
Regular Calibration
Emission analyzers use chemical sensors that need to be calibrated periodically to ensure measurement accuracy. Most come with user-defined calibration periods. Follow it carefully.
Sensors
Like the other parts of the meter, the sensors degrading over time is a very common phenomenon. Some modern analyzers are equipped with extended sensors to allow up to 100K readings at most. However, it is advisable to replace the sensors after the recommended time by the manufacturer, even if the emission tester is working fine.
Sensor Technology
In portable emission analyzers, sensor quality is crucial for accuracy and reliability, as it is the main component that measures gas concentration. Advanced models use electrochemical, infrared, or laser technology sensors to analyze and measure emissions.
Build Materials
With time, the analyzer should be able to keep its measurement accuracy. This depends on how the various parts, inside and outside, are built. For instance, an LCD screen is better than a regular one because it is more durable against outdoor conditions. Analyze what material is used to make each part. It directly affects itself in measurements and overall durability.
Standards Compliance
Make sure to get emission analyzers that meet international standards, at least one of them, whether ISO, EPA, or CE. These certifications are signs of quality and reliability.
Data Accuracy
Data accuracy is crucial because the main purpose of using portable emission analyzers is to get accurate emission levels. In simple terms, data accuracy refers to how precise the collected data is compared to the real situation of the emission. Precision means the ability to get the same result over and over again, even if the result is wrong. Emission analyzers typically use electrochemical sensors, infrared sensors, and laser sensors to get accurate data. Each sensor is chosen depending on the gase to analyze. After that, the gathered data is analyzed using signal processing technology and displayed on the screen to the operator.
Hazardous Gas Handling
Toxic and flammable gases, such as carbon monoxide and methane, are automatically detected by emission analyzers. These gases can cause emission to pose serious threats, such as suffocation, fire, or explosion.
Follow Personal Protective Equipment Guidelines
It isn't compulsory to wear PPE while carrying out emission tests in the open atmosphere. However, it is highly recommended to wear appropriate protective clothing—personal protective equipment, such as gloves, safety glasses, and hard shoes—when handling toxic or flammable emission gasses in confined or low-ventilation spaces.
Explosion Proof
Always prefer emission analyzers that are intrinsically safe or high IP or NEMA rated for emission environments where the emissions are likely to be explosive. For example, IP66 rated instruments are safe for analyzing gases that may get inside the instrument and generate dangers, like oxygen.
Proper Storage
A portable emission analyzer might be damaged if exposure to high or low temperatures, humidity, or chemicals. In addition, some room emission analyzers use sensors that need special treatment—storage in a specific environment, for example, oxygen-sensitive sensors that require storage in a low oxygen atmosphere.
Handling and Maintenance
Analysers consist of electrochemical cells or infrared diodes to measure gases, each sensitive to one or several gasses. Although these sensors are well protected and sealed, a very small amount of emission can damage them. When opening or touching an analyzer, always wash hands afterward to ensure no harmful substances are on them that could get into the sensors.
The portable analyzer uses two main methods to determine or analyze emission levels: gas sampling and gas conditioning. In gas sampling, a probe is used to capture emitted gas, which is then analyzed using chemical sensors to measure its concentration. On the other hand, in gas conditioning, pollution control devices such as scrubbers and filters are used to reduce emission pollutants.
They are more compact, user-friendly, and adaptable, with important factors like real-time analysis, automatic recording, and built-in calibration for maximum efficiency. Hence, they are the right choices for spot checks, emergency response, field testing, and troubleshooting. In other words, they are suitable for mobile applications. Only one drawback—less precise than stationary ones—that is no longer valid with recent technological advancements.
In a power plant, for example, increasing temperature causes fuel to burn more completely, resulting in lower carbon monoxide and hydrocarbon emissions. On the other hand, higher temperatures can increase the formation of nitrogen oxides thanks to the combustion process.
Fortunately, almost all industries that deal with air pollutants, such as oil and gas, chemical manufacturing, and metals, benefit from portable emission analyzers. All these industries need an efficient way to monitor emissions to comply with regulations. For example, the automotive industry uses it to analyze tailpipe emissions. On the other hand, power plants in the energy sector use it to monitor emissions from combustion.
