Rich-burn engine exhaust, when uncontrolled, can have wide concentration ranges and both CO and NOX can fluctuate significantly. The on-board CO dilution system will automatically set-up for optimum testing, perfect for a rich burn engine. Lean-burn engines have different exhaust characteristics, but NO2 can make up a significant portion of the total NOX measurement. The 350 measures both NO and NO2 for proper lean-burn engine set-up.
Due to high concentration, replaceable interference filters keep the sensors...

Our sample conditioning instruments can be connected to any particle measurement instrument and allow engine exhaust measurements from various conditions and engines. Both dynamometer and on-board conditions. CVS...
The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a...
Dekati measurement solutions for determination of particulate emissions from engines include both particle detection and sample conditioning solutions. For non-road and off-road emission measurements, we have complete measurement solutions both upstream and downstream exhaust after-treatment devices. The exhaust sample conditions in marine and aircraft engine emission measurements may vary a lot depending on the type of engine, type of fuel and also measurement location. Our sample conditioning instruments can be...
There are many types of stationary and mobile internal combustion engines that can run off gas or diesel fuels. Engines can be lean burning at a high air to fuel ratio (AFR) or rich burning at a low AFR. The exhaust stack gases from engines contain pollutant gases including CO, NO, NO2, NOx, and CxHy hydrocarbons as well as particulate matter. Measuring the engine exhaust emissions is important for engine tuning, performance optimization, safety, and proving emissions compliance to regulatory authorities.
After the proliferation of the Clean Air Act in 1970, the catalytic converter for automobiles was introduced as probably the most important technology in History to clean air pollution worldwide. Removing Carbon monoxide (CO), Hydrocarbons (HC) and nitrogen oxides (NOx), the catalysts contributed substantially to the elimination or reduction of smog in major cities in the USA and Worldwide.
When extracting and refining valuable geological materials from the earth (eg. limestone, aluminum oxide, gold), a variety of industrial combustion processes are required. The machinery used in these processes such as industrial engines, boilers, and smelters can emit highly toxic gases that are harmful to the environment and to human life. Using a portable emissions analyzer enables mining personnel to ensure personal and environmental safety, while optimizing the performance of the mining operation.
With vessels, such as MS Harmony of the Seas or MSC Oscar, getting bigger and bigger, pollutions issues are becoming more relevant daily as they cruise along our coasts. Regulations are becoming tighter to reduce the NOx, SOx and Green House Gases emissions. More information can be found on the IMO Marine Engine Regulations. Our instruments have been designed to help local maritime authorities monitor such gases (NOx, SOx, GHG) and to help designing fuel with lower sulfur content.
Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, and measure and reduce harmful emissions in the forklift engine exhuast gas.
As exhaust emissions from engine tailpipe have been decreasing in recent years through development of engines and exhaust after-treatment systems, non-exhaust emissions have become a major contributor to total particle emissions from vehicles. Dekati provides complete measurement solutions for brake wear and blow-by gas emission measurements and we can cover the complete particle size using only one measurement method – 6 nm – 10 µm with one measurement method.
Marine vessels can emit air pollution such as CO, CO2, NOx (NO+NO2), and SO2 from their diesel engines and onboard incinerators. MARPOL Annex VI and the technical code for control of emissions of nitrogen oxides (NOx Technical Code) issued by IMO are internationally recognized regulations for the prevention of air pollution and emissions from marine vessels. Ships over 400 gross tons are also required to have an International Air Pollution Prevention (IAPP) certificate which can be obtained by confirming compliance...
E Instruments International’s gas monitoring specialists performed a forklift exhaust gas analysis and an ambient air quality analysis at a Pennsylvania warehouse in which a fleet of propane forklift trucks is operated on a daily basis. The main objectives of these tests were to investigate:
The IMO (International Maritime Organization) continuously sets new standards in order to minimize and control the harmful polluting exhausts from vessel engines. IMO is the World’s largest maritime organization with over 170 member states and acts as a regulatory agency for the international maritime industry.
Facilitates Data Management for Tank Emissions Reporting; VisionMonitor Software leverages existing technology investments you have deployed to run your current operations. It simplifies the process of gathering tank inventory data by linking to existing internal systems, automating data collection from these systems via a scheduler, and by providing a path for manual input when required for sources such as diesel engines, package boilers, etc.
Cogeneration, or combined heat & power (CHP), is the utilization of boilers, turbines, and/or engines to simultaneously generate electricity power and heat that can be useful in several ways such as for hot water, steam, district heating, and water desalination.
Fixed CEMS (Continuous Emissions Monitors) Measure at One Location
CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.
If the CEM is measuring emissions that are higher than the regulated or permitted limits, it can be difficult to determine the source of the high emissions which could be from...
Everyone has a responsibility to care for the environment to reduce the levels of pollution, including businesses that daily release emissions into the air and the ground. This is why we provide a full-service environmental testing service to help businesses identify problems and resolve them so they operate in the most environmentally-friendly method possible. We offer air emission testing, emissions monitoring services and stack emissions testing to businesses of all sizes.
A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.
PLAZKAT Aero systems are used to treat emissions from motor and railroad vehicles. It has been found that exhaust gases from internal combustion engines (ICE) contain over 250 ingredients. Major components include carbon oxides, nitrogen oxides and hydrocarbons.
