NO: (0~4,000) ×10-6 vol; (4,001~5,000) ×10-6 vol
NO2 (only NHA-509V): (0~400) ×10-6 vol; (401~1,000) ×10-6 vol

Details

The analyzer adopts the NDIR principle to measure the content of CO, HC and CO2, and the electrochemistry principle to measure the content of NO and O2 in the exhaust smoke from the gasoline engine, and finally obtain the excess air coefficient λ based on the content of CO, CO2, HC and O2.


Features

  • Adopt cutting-edge technologies.
  • Equipped with microprocessor and touch screen.
  • Comform to the latest regulations for Class 00 instruments according to OIML R99/2000(E), ISO 3930, and JJG 688.

Applications

Applicable to vehicle inspection stations.
