Automotive Emission Analyzer

NHA-501A f i v e - g a s Automotive Emission
Analyzer is used to measure the concentration of HC,
CO, CO2, NO and O2 contained in exhaust gases from gasoline vehicle engine. It is equipped with Chinese or English menu, LCD screen, automatic zeroing, automatic calculation and display of air fuel ratio . It can also make a comprehensive test for combustion and exhaust pollution. The instrument is assembled with imported key components and sensors by adopting advanced overseas technology. With the function of time and date display, 800 groups of data storage and review, RS-232C serial digital communication interface, it can be connected with external printer. The revolving speed can be tested under idling / dual idling speed with the supply of standard part inductive speed measuring pliers and optional part oil temperature probe accessories.
