Calibration Gas for Exhaust Gas Monitoring
Good air quality is the premise of sustainable development of human society. With the rapid development of motor vehicle economy, the production and usage of motor vehicles have increased rapidly, and the pollution of motor vehicle exhaust to the environment is becoming more and more serious. It has become an important source of urban air pollution, causing serious harm to the environment and people's health. Accurate, stable and traceable reference material is a necessary prerequisite for the smooth progress of this work.
Most of the reference material meeting the requirements of exhaust gas monitoring and control standards are available, as listed below. Meanwhile other calibration gases can be customized as required by customers.
