NHA-406/506 Gas Analyzer

To measure the concentrations of HC, CO, CO2, O2 and NO, and λ of the exhaust gas from motor vehicles.

Classification:

Product Center

Vehicle Inspection

Gas Analyzer

Product Documentation:

Measuring Range:
HC: 0~9,999×10-6 (hexane equivalent)
CO: 0~10×10-2 (%)
CO2: 0~18×10-2 (%)
O2: 0~25×10-2 (%)
NO: 0~5,000×10-6 (only NHA-506)

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. Capable of performing multi-mode dual-speed idle test on gasoline, natural gas (LNG/CNG), liquefied petroleum gas (LPG), ethanol gasoline, and various fuel-powered vehicles.
