At CME Laboratories Bharat Pvt Ltd, we deliver comprehensive oil analysis services to ensure the health and longevity of your critical equipment. By monitoring lubricant condition and machine wear, we help you prevent costly breakdowns, optimize maintenance, and extend asset life.
Diesel Exhaust Fluid (DEF), also called AdBlue®, is a non-toxic, high-purity solution that reduces harmful gases being released into the atmosphere. DEF is designed to be used in Selective Catalytic Reduction (SCR) systems for diesel engines. When used in an SCR system, it can significantly reduce harmful oxides of nitrogen (NOx) released from diesel engine exhaust. SCR is one of the most efficient and cost-effective means of meeting serious emissions regulations. SCR uses DEF, which is now heavily adopted in commercial vehicle, and heavy machinery, where diesel emissions are significant.
At CME Labs, we offer a comprehensive range of DEF testing services in full compliance with ISO 22241 standards, ensuring your DEF meets the required purity and performance standards.
Diesel exhaust fluid (DEF) plays a critical role in reducing harmful NOx emissions through the SCR system. Contaminated or inferior DEF will cause damage to SCR systems, can damage engine components, and compromise emissions performance.
Ensure Compliance with ISO 22241 Standards
Verify that your DEF meets the global benchmark for purity, concentration, and performance.
01
Protect Your SCR System
Detect and avoid harmful contaminants like metals, phosphate, or excessive biuret levels.
02
Maintain Optimal Emissions Control
Ensure your vehicle stays within legal emission limits and runs efficiently and cleanly.
03
Maximize Fuel Efficiency High-quality
DEF supports better combustion, which can help improve fuel economy and overall engine performance.
04
What is Diesel Exhaust Fluid (DEF) Testing?
DEF testing is the process of gathering and testing a fluid sample to analyze the purity, composition, and suitability for use in SCR systems.
Our lab examines:
Urea Concentration – to verify the correct chemical strength for NOx reduction
Contaminants – including metals, phosphate, biuret, and insoluble matter that may harm SCR systems
Key Quality Parameters – such as refractive index, alkalinity (as NH₃), aldehydes, and trace elements
DEF with the SCR system converts harmful NOx emissions into harmless nitrogen and water vapor
Extend Engine Life. Maintain Emission Efficiency. Make Maintenance Predictive.
