MQW-50B Motor vehicle exhaust analyzer Measure and analyze the components of motor vehicle exhaust
Product Introduction:
This product measures CO, HC, CO₂, and NO within motor vehicle exhaust based on NDIR, measures O₂ based on electrochemistry theory, and calculates excess air coefficient λ from the measured CO, CO₂, HC, and O₂ values. It is in compliance with GB 18285-2018. It is suitable for motor vehicle inspection station, automobile works, automobile repair workshop, motorcycle repair workshop, etc.
